[OJS3] Problem with search


I’m having a lot of trouble with the OJS search functionality. It seems to work for some journals, for others it works partially and doesn’t seem to index all articles.

I have redo the indexing many times running the rebuildSearchIndex.php and although it takes time it completes with no apparent errors, just a few warnings

I’m using OJS and I mos update it soon
Can anyone help me with this issue?
