Best practices to configure full-text search

This configuration checklist describes best practices for configuring the full-text-search (FTS) component of the out-of-the-box AR System platform installation for the Remedy 9.1 release. It applies to all releases of 9.1.x. The document may be updated as more testing and observation is complete. We recommend that you check for updates periodically.

General recommendations

  1. We recommend putting FTS Indexer on a Backend Server.

  2. SmartIT uses FTS and MFS more than standard ITSM, so we recommend adding FTS resources for support.

  3. For environments that heavily use FTS and MFS, set up multiple indexers.
  4. If there are multiple Indexers, none must be on the user-facing servers.
  5. At present, the Load Balancer testing is from the Searcher Plug-in Servers, which has been implemented and tested, but is not a best practice as yet.
  6. Make sure to have enough capacity on the secondary FTS server in case the primary FTS server fails.

AR System Server and plug-in server settings

*Recommend HA setup.
** The value of this parameter will change based on usage and environment.

We recommend the FTS Search Threshold to be 2000.
Make sure to test whether this value is acceptable to be able to find the records.

Garbage Collector settings

We recommend using these Garbage Collector (GC) parameters (same as AR System server) with the plug-in Server for FTS.
