I am sorry to bring more problems to the table, but the indexing of lexemes in the "ordinary" elasticsearch-based search is now also often slow. The Q-items are also indexed slowly, but there you can at least type in the Q-number in the edit field and it will lookup the item. For L-numbers, I have not found a way to type in and one would have to wait for some minutes before L-items are indexed.
An example use case is the entry of "fordømme" and "dømme" where one links to the other by P5238, see https://www.wikidata.org/wiki/Lexeme:L245454. As is apparent from the edit histories, I waited over 10 minutes for the indexing before I could link the two lexemes.
