Connect to Google Search Results in CloverDX (formerly CloverETL)

The CData JDBC Driver for Google Search enables you to use the data transformation components in CloverDX (formerly CloverETL) to work with Google Search as sources. In this article, you will use the JDBC Driver for Google Search to set up a simple transfer into a flat file.

Connect to Google Search as a JDBC Data Source

1. Create the connection to Google Search results. In a new CloverDX graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
2. Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.googlesearch.jar file.
3. Enter the JDBC URL.

   To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

   To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

   To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Google Search JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.googlesearch.jar

   Fill in the connection properties and copy the connection string to the clipboard.

   A typical JDBC URL is below:

   jdbc:googlesearch:CustomSearchId=def456;ApiKey=abc123;

Query Google Search Results with the DBInputTable Component

1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
2. In the DB connection property, select the Google Search JDBC data source from the drop-down menu.
3. Enter the SQL query. For example: SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'

Write the Output of the Query to a UniversalDataWriter

1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
3. Right-click the DBInputTable and then click Extract Metadata.
4. Connect the output port of the DBInputTable to the UniversalDataWriter.
5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the VideoSearch table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
6. Click Run to write to the file.
