TYPO3 Core

Searching with indexed_search for a term (word) with a large number of results throws exception:

An exception occurred while executing

System environment¶

TYPO3 version 8.7.20

Steps to reproduce¶

1. Get installation with a large number of pages / words.
2. Search for a term that is common on those page.

(I could probably test to get the exact number, but I assume, someone knows this without tedious tests).

Exception¶

Exception is thrown in IndexSearchRepository::execFinalQuery when $queryBuilder->execute is called. There may be other occurances.

Best to generally search for expr()->in(

Comment¶

As indexed_search is not suited for large installations and this may not get fixed, I think at least the docs should name the restrictions specifically, e.g. what exactly are the limits, e.g. number of pages, number of words, if possible.
