Major Description
There is a built-in full-text engine that is used for full-text queries if no full-text index (Lucene, Solr) is available.
This built-in engine tries to load binaries in memory, which can result in out-of-memory.
We either need a way to disable this built-in mechanism (in which case the query engine would throw an exception for full-text queries), and / or change the built-in mechanism so it doesn't result in out-of-memory.
