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)
Note: For your query you will need to replace the ip address 192.168.1.10 to your GSA server ip address.
- 2. Create a simple sample GSA http query and test; for instance we will search the word product and the query will be: http://192.168.1.10/search?q=product&output=xml&client=default_frontend&site=default_collection&filter=0
- 3. 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
- 4. Create a dynament like GSASearch.xml and include the following content:
<rde-dm:attribute mode="write" source="request" attribute="gsaHost" value="192.168.1.10" />
<rde-dm:include tag="generalResults" content="http://[#request:gsaHost#]/search?q=[#request:param#].encode()&output=xml&client=default_frontend&site=default_collection&filter=0" rde-id="01"/>
- 5. 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.
- 6. Create an xslt file to format the results from Google.
