This page provides a guide to Establishing a Connection to Google Search in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to Google Search

Establishing a Connection shows how to authenticate to Google Search and configure any necessary connection properties to create a database in CData Cloud

Accessing Data from CData Cloud Services

Accessing data from Google Search through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.

Connect to Google Search by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.

Connecting to Google Search

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.

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

Creating a Custom Search Engine

To start searching websites through the Cloud, 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.

Getting 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.

Customizing the SSL Configuration

By default, the Cloud 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.

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

The CData Cloud 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 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.

CData Cloud - Google Search Views

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

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.

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, "*=*".

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 Cloud throws an exception.
