Welcome to the Atlassian Community!

You should index the whole system whenever you make a structural change to it, such as a change of database collation, a migration, or change of indexing language, or you have an event that means the index may be damaged (some form of crash or running into a bug)

The rest of the time, Confluence will index changes as you use it, so you should not have any need to run a full re-index in between upgrades (upgrades run one as part of the process)

There a db upgrading ,

Currently, in backend there content index value alike not found.

A standard Confluence upgrade will run a re-index for you, but if you upgrade the database server, that could be what I called "a structural change", and I'd recommend a re-index then too.  So, yes, good call.  But you only need to do that once after each upgrade, it's not a regular occurrence.

Where are you seeing this "context index value alike not found"?  It's not a message I recognise, but it is similar to one I have seen when you have broken data in your database (if it is that, then a re-index won't fix it, but it is not a huge problem, it just means your searches might miss the pages that have the problem)

673 WARN [Caesium-1-2][ Contentproperty.index.extractor.ContentPropertyExtractionManagerImpl]

Those are from Tomcat, they're nothing to do with the Jira index.

Ic , thanks for the info. Need to look for Tomcat expert. how to resolve it.

You don't need to worry about it, it's a warning for people doing advanced Tomcat configuration (which you don't need to think about when running Jira)

Hi @keewan lew

welcome to the Atlassian Community.

There should be no need to rebuild the indexes on a regular basis, according to the documentation: https://confluence.atlassian.com/doc/content-index-administration-148844.html
Is there a specific problem that is to be solved on your instance?

Regards,
Daniel

Hi @keewan lew ,

Automatically rebuild indexes regularly?

btw, what is the purpose of doing this?
