Marking this one 'later'; would be dependent on having the general infrastructure for full-history search in UI and updating (bug 10643).

As an interim solution, you can use the Diffdb ( and Wikihadoop ( for this. Contact me if you want to know more.

For future reference, please use either RESOLVED WONTFIX (for issues that will
not be fixed), or simply set lowest priority. Thanks a lot!]

We're migrating from Lucene to CirrusSearch. Moving this bug accordingly.

This feature probably makes the most sense on a per-page basis, e.g. the user story "As an editor, I want to be able to search the history of a specific page so I can know if certain information was added into the page and removed.".

Also, title fix.

Actually the more I think about it, this is going to be a WONTFIX for MediaWiki & Cirrus. Search is inherently about finding information that's currently on the wiki. Plus storing all the revisions of the page would basically double our storage requirements for what's essentially a power-user feature.

For history searching, we have dumps.

essentially a power-user feature.

power users don't matter?
