Text indexing stopped working

[Mikael Pesonen]

What could be the reason why new data is suddenly not added to text 
index and not found with Jena text queries?

The newest files in Jena text index folder are zero sized
_b_Lucene85FieldsIndexfile_pointers_n.tmp
_b_Lucene85FieldsIndex-doc_ids_m.tmp

dated 2023-11-13 although I have added lots of data since then using 
same methods as before. Text queries find all the data before this date.
