Searchable plugin with Tomcat

[Maharaj thak]

Hi
I am creating a Grails app and trying to deploy it on jelastic.com.I have 4 Tomcat instances running.In my Searchable.groovy file I have made a change to the path where the index file is stored.

compassConnection = new File(
"/opt/tomcat/temp/searchable-index/${grailsEnv}"
).absolutePath

Does each instance of Tomact has its own index file or will all the 4 instances point to the same index file?

Regards
