This tip came about because we came out with security patch that only affected FAST Search for SharePoint 2010 deployments that have the ‘Advanced Filter Pack’ enabled. By default, it is disabled. My customer wanted to definitively check to see if it was enabled in order to prepare to install the security patch.
How to check:
Option 2: Go to \FASTSearch\etc\config_data\DocumentProcessor\optionalprocessing.xml. In that file there is a line like this: <processor name="SearchExportConverter" active="no" />
If it is enabled, active will be set to “yes”
