Hello,
On nearly all my 4.7 sites, I am having problems with search. The issues are random, but occur on all my sites. After a certain amount of time, results stop being indexed. My search index tells me that all is indexed, though I know, it is not :) When I search for obvious words in newer posts, I get either no results, or too few.
Rebuilding the index works. Untill after a random time, then it stops indexing. Indexing stops on one site a time. This has been going on for months.
Cron runs just fine, so it seems, and I /am/ running multisite sites, with cron runs on all the sites every 16 minutes, so it could be a memory/CPU issue, though I doubt it, since my watchdog tells me cron ran just fine, and my server is far from choked.
Has anyone experienced this too? Has anyone seen any docs on Drupal.org about this specific issue? Does anyone know where to start debugging this weirdness?
