Google Search Connection Details

Introduction

Connector Version

This documentation is based on version 23.0.8936 of the connector.

Get Started

Google Search Version Support

The connector enables you to execute SQL to Google Custom Search Engines.

Establish a Connection

Provide the following connection properties before adding the authentication properties.

  • CustomSearchId: Obtain this value by signing into Google Custom Search Engine and creating a new search engine.
  • APIKey: You must enable the Custom Search API in the Google API Console.

For more information on obtaining values for these properties, refer to Connecting to Google Search.

Connect to Google Search

To establish a connection to Google Search provide a CustomSearchId and APIKey.

Create a Custom Search Engine

To start searching websites through the connector, follow the steps below:

  1. Sign into the Google Custom Search Engine site.
  2. Click New Search Engine and add a site to focus the search on.
  3. Click Edit Seach Engine, select your search engine in the menu, and then click Setup.
  4. In the Details section, click Search Engine ID to retrieve the search engine ID used as the CustomSearchId in the connection string.
  5. In the Sites to Search section, you can additionally select the Search the Entire Web but Emphasize Included Sites option in the menu.

Get the API Key

To authenticate requests to the Custom Search API, follow the steps below:

  1. Log into the Google API console and select a project.
  2. In the side bar under APIs & Services, click Library and then select the Custom Search API. Click Enable.
  3. In the side bar, click APIs & Services -> Credentials.
  4. Click Create Credentials -> API Key.
  5. Select the API Key to restrict the key to your platform.

You can now search the Web using the Google Custom Search engine.

Important Notes

Configuration Files and Their Paths

  • All references to adding configuration files and their paths refer to files and locations on the Jitterbit agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Advanced Features

This section details a selection of advanced features of the Google Search connector.

User Defined Views

The connector allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Proxy

To configure the connector using Private Agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.

Query Processing

The connector offloads as much of the SELECT statement processing as possible to Google Search and then processes the rest of the query in memory (client-side).

See Query Processing for more information.

User Defined Views

The Google Search connector allows you to define a virtual table whose contents are decided by a pre-configured query. These are called User Defined Views, which are useful in situations where you cannot directly control the query being issued to the driver, e.g. when using the driver from Jitterbit. The User Defined Views can be used to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.

There are two ways to create user defined views:

  • Create a JSON-formatted configuration file defining the views you want.
  • DDL statements.

Define Views Using a Configuration File

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM WebSearch WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"

Define Views Using DDL Statements

The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.

Create a View

To create a new view using DDL statements, provide the view name and query as follows:

CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;

If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.

Alter a View

To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:

ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';

The view is then updated in the JSON configuration file.

Drop a View

To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.

DROP LOCAL VIEW [MyViewName]

This removes the view from the JSON configuration file. It can no longer be queried.

Schema for User Defined Views

User Defined Views are exposed in the UserViews schema by default. This is done to avoid the view's name clashing with an actual entity in the data model. You can change the name of the schema used for UserViews by setting the UserViewsSchemaName property.

Work with User Defined Views

For example, a SQL statement with a User Defined View called UserViews.RCustomers only lists customers in Raleigh:

SELECT * FROM Customers WHERE City = 'Raleigh';

An example of a query to the driver:

SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';

Resulting in the effective query to the source:

SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';

That is a very simple example of a query to a User Defined View that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.

SSL Configuration

Customize the SSL Configuration

By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Data Model

The Google Search connector models Google Custom Search engines as relational databases, which can be accessed with SQL-based tools.

This chapter describes the view behavior and provides examples of how to execute queries to Google Custom Search engines. Views are tables that cannot be modified. Typically, read-only data are shown as views. View schemas are defined in simple, text-based configuration files.

Views

Views are similar to tables in the way that data is represented; however, views are read-only.

Queries can be executed against a view as if it were a normal table.

Google Search Connector Views

Name Description
ImageSearch Query Google custom search engines for images.
WebSearch Query the web on Google.

ImageSearch

Query Google custom search engines for images.

Table Specific Information

When querying this table the SearchTerms parameter must be specified. For example, to search in ImageSearch for the term 'technology' use the following query:

SELECT * FROM ImageSearch WHERE SearchTerms = 'technology'

To filter out certain queries and include other queries, use a mix of operators on the SearchTerms field:

SELECT * FROM ImageSearch WHERE SearchTerms = 'search1' AND SearchTerms != 'search2' AND SearchTerms > 'x' AND SearchTerms < 'y' OR SearchTerms = 'or this'

To include a site in the search, execute a query like the following:

SELECT * FROM ImageSearch WHERE SearchTerms = 'technology' AND Site = 'https://wikipedia.com/'

Likewise, to exclude a site from the search, execute a query like the following:

SELECT * FROM ImageSearch WHERE SearchTerms = 'technology' AND Site != 'https://wikipedia.com/'

Google search has an aggregate function called TotalResults() that is similar like Count(*).

TotalResults() can be used if you want to get the number of result based on your query.

The Google Search API limits the number of item returned to 100 so count(*) will not be the actual number of search results.

SELECT TotalResults() FROM ImageSearch WHERE SearchTerms = 'ancient artifact'
Columns

Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

Schema

This section provides a complete list of schema properties you can configure.

Property Description
Location A path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemas This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC.
Tables This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA, TableB, TableC.
Views Restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC.

Location

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Data Type

string

Default Value

%APPDATA%\GoogleSearch Data Provider\Schema

Remarks

The path to a directory which contains the schema files for the connector (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is "%APPDATA%\GoogleSearch Data Provider\Schema" with %APPDATA% being set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Mac ~/Library/Application Support
Linux ~/.config

BrowsableSchemas

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Data Type

string

Default Value

""

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

Tables

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Data Type

string

Default Value

""

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Views

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Data Type

string

Default Value

""

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Miscellaneous

This section provides a complete list of miscellaneous properties you can configure.

Property Description
MaxRows Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Other These hidden properties are used only in specific use cases.
PseudoColumns This property indicates whether or not to include pseudo columns as columns to the table.
Timeout The value in seconds until the timeout error is thrown, canceling the operation.
UserDefinedViews A filepath pointing to the JSON configuration file containing your custom views.

MaxRows

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

Data Type

int

Default Value

-1

Remarks

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

Other

These hidden properties are used only in specific use cases.

Data Type

string

Default Value

""

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting
Property Description
DefaultColumnSize Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT Determines whether to convert date-time values to GMT, instead of the local time of the machine.
RecordToFile=filename Records the underlying socket data transfer to the specified file.

PseudoColumns

This property indicates whether or not to include pseudo columns as columns to the table.

Data Type

string

Default Value

""

Remarks

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".

Timeout

The value in seconds until the timeout error is thrown, canceling the operation.

Data Type

int

Default Value

60

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the connector throws an exception.

UserDefinedViews

A filepath pointing to the JSON configuration file containing your custom views.

Data Type

string

Default Value

""

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM WebSearch WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json

Note that the specified path is not embedded in quotation marks.
