Lucene rebuild issue

[gouwzee]

Some years ago I noticed that Lucene wouldn't finish indexing in a rebuild. Since then I anxiously refrained from rebuilding the index.
A couple of days ago we finally tried.. Unfortunately the indexing problem doesn't seem resolved in our current version (10.1.0). Although it indexed quite a lot, it failed to index the page titles. A major issue in everyday searching.
Would upgrading to 10.1.3 resolve the problem?

I also consider restoring the old index out of a backup tar. What files would I have to restore?

Thanks!

Kind of stupid to post my own answer, but maybe ticket 9950 addressed the issue?

That issue was about re-indexing taking down a site if there was too much content since it tried to do everything at once.

Our wiki is upgraded now to the most recent version, but the problem remains, indeed.
Any suggestions what to do?

It is unfortunate that no one seems to have any idea what to do. :-(
It is a major setback for the adaptation of my dekiwiki; people rely on the search engine to navigate our 6K+ pages and may reconsider using it when the search engine cannot even find page titles.

I did notice that page edits invoke a re-indexation of a page. I Would it be possible to use some kind of finger/touch command to run through all pages? I do have the possibility to do it with my own code.

Looking at the API documentation, there is a POST http://servername/@api/deki/pages/{pageid}/index?apikey=APIKEY operation to tell the search engine to just reindex that one page. You could write a script that gets all page IDs from the db, then issues the page re-index operation in batches so as to not overwhelm the full reindex operation.

I will give this a try. Thanks!

I got it working! In my home dekiwiki I did not need the apikey flag and my work dekiwiki I did. Don't quite understand why that is. But I am getting search results!!! :-)
Is there an api command that returns the api key?
