oshyn: OpenText™ Web Solutions Delivery Server / LiveServer and Google Search Appliance (GSA)

by: Diego Vergara

Even though Live Server comes integrated with Verity as a search engine, it is possible to use Google Search Appliance (GSA) as a search engine on a Live Server site.

The Advantages we have for using GSA are:

  • Independent administration console.
  • User search familiarity.
  • Fast search engine with an inbox server.
  • Google custom searches and weights for pages.
  • Google technical support.

Now how would we pass the request to GSA. First GSA lives in a separated server which will be connected to Live Server by, if possible, a gigabit infrastructure.

GSA is nothing more than a web application that gets http requests and based on the parameters returns an html or xml response. 

Knowing this, to integrate GSA with Live server we will need to create a dynament which will include the xml response from GSA and then format with a traditional xslt similar to the ones we use for the rest of the site.

So in brief the steps to integrate GSA will be:

  1. Set up GSA and index the site (see GSA)
  2. Create a simple sample GSA http query and test; for instance we will search the word product and the query will be:

Note: For your query you will need to replace the ip address to your GSA server ip address.  

  1. Copy the google.dtd file to the following location C:\Program Files\RedDot\LiveServer\tomcat\bin\google.dtd. This file permits Live Server to process the xml response from Google. Please note that we are considering the default installation of Live Server on a Windows Server
  2. Create a dynament like GSASearch.xml and include the following content:
  <rde-dm:attribute mode="write" source="request" attribute="gsaHost" value="" />
  <rde-dm:include tag="generalResults"  content="http://[#request:gsaHost#]/search?q=[#request:param#].encode()&amp;output=xml&amp;client=default_frontend&amp;site=default_collection&amp;filter=0" rde-id="01"/> 
  1. Test the dynament calling with the parameter param to see the results, for instance GSASearch.xml?param=product. This should return the same result from step 2 but from a live server request.
  2. Create an xslt file to format the results from Google.
