Fulltext Search Not Working in Own Channels – “Table handler out of memory” Error

I am experiencing a persistent problem with the fulltext search in my own channels on this Friendica instance. No matter which term I search for—even a single word—the search does not work and I always receive the error message:
“Table handler out of memory”

Maybe there are some settings on the server side that need to be adjusted so that the search feature works reliably again.
