Google Search Sources¶
Note
The Google Search feature is deprecated and it may be removed in future major versions of the Denodo Platform.
The section Features Deprecated in Virtual DataPort 7.0 lists all the features that are deprecated.
Virtual DataPort can extract data from the “Google Search Appliance” (GSA). Google discontinued this product in 2019. The Google Search Appliance (GSA) is a rack appliance that indexes the websites and documents of your organizations. You can query these indexes from Virtual DataPort.
To create a new Google Search data source, right-click on the Server Explorer and click New > Data source > Google Search.
The Tool will display the dialog to create the data source.

Importing a new Google Search data source¶
The following data are requested in this dialog:
Name. Name of the new data source.
Host name. Name of the machine in which the search engine is accessible. This may be a remote machine accessible on the Internet (e.g. “search.acme.com”).
Port. Port on which the Google Search service listens (usually 80).
Proxy Configuration. If the connection is established through a proxy, you have three options:
Select Manual and enter the host name and port of the proxy server. If it is an authenticated proxy, enter the user identifier and the password of the proxy.
Select Default. The Server will use the default HTTP proxy configuration of the Server (see section Default Configuration of HTTP Proxy).
Select Automatic and enter the URL of a
proxy.pac
file that contains the configuration parameters of the proxy.
In the Metadata tab, you can set the folder where the data source will be stored and provide a description.
When editing the data source, you can change its owner by clicking the
button .
Click Save to create the data source. Then, click Create base view to see the schemas stored in the Google Search engine.

Description of a Google Search data source¶
Click Create Base View to create a base view associated with the new data source (see Creating a Google Search base view).

Creating a Google Search base view¶
A value can be specified for the following parameters at the top of the screen:
Site Collections. Required. It specifies the collections within the Google Search server on which to make the search. The collections are created by the Google server administrator. Its name is upper/lower case-sensitive. It is possible to specify several collections separated by commas. In this case, the search will be made on all of them. The collection that is being searched by a particular search form can normally be obtained by examining the value of the site parameter of its invocations.
Client. Optional. It identifies the client making the queries. Google Search servers can be configured to behave differently depending on the client.
Languages. Optional. If specified, only documents in that language will be returned.
Number of Key Match. Optional. Google Search allows the administrator to manually set a priority of the pages. This parameter receives an integer between 0 and 5, where 5 is the top priority. If this value is established, the searches made on this base relation will only return the pages with the priority specified or over.
The value of these parameters can be modified later, on the “Options” dialog of the base view (see section Configuration Properties for Specific View Types).
The name and type of the fields can be modified. The contents of each one of the attributes is:
TITLE
. Title generated by Google server for the document.SUMMARY
. Summary generated by Google server for the document.URL
. Document URL.MIMETYPE
. MIME type of the document.RATING
. Priority assigned by the Google server administrator for the document. This may take values of between 0 and 5, where 5 is the maximum priority.MAXDOCS
. Attribute that limits the maximum number of results returned by a search.METAS
. Attribute of Array of records type that contains the metatags for the document. Each record has two fields to indicate the name of the metatag (metakey
) and its value (metavalue
).CONTENT
. Contents of the document. This is the field normally used for searches.SITE
. If specified, Google server will only return the documents that belong to that site / collection (e.g. “acme.com”).FILETYPE
. Extension of the document file.
In the Metadata tab, you can set the folder where the base view will be stored and provide a description.
When editing the base view, you can also change its owner by clicking
the button .
Then, click Save to create the base view.
The most common way of querying the Google Search base view is using the
CONTAINS
operator, which runs complex Boolean searches on indexed
textual data (see the section Support for the Contains Operator of Each Source Type of the VQL Guide).
