Hi Amit,

I believe the two documents below should help you with your question:

* https://confluence.atlassian.com/display/JIRA/Search+Indexing
* https://confluence.atlassian.com/display/JIRA/Re-Indexing+after+Major+Configuration+Changes

They also provide clarification as to when you should perform a re-index.

I hope this information helps.

Cheers,

Danilo

Running vast punts of searches against a database is a performance killer, so jira keeps a local and optimised and indexed chunk of data locally.  This makes the whole system a lot faster. Rebuild index does what it says.  Removes the  current index and rebuild s a new one.  In general, you can ignore it.
