[Koha-devel] labels/label-item-search.pl hardcode queries that only work with Zebra

Hello all! Seems I'm diving into ES these days.  We have an issue with labels/label-item-search.pl which uses the search engine to find items, but the code hardcodes (acqdate,ge:2022-02-17) Which the ES's build_query_compat() method doesn't handle.  ES's index is date-of-acquisition. The right way to solve this would be to fix the query parser, but that's a tall task for me.  Another way would be for me to cheat, if only I knew what form the proper query would look like in ES. Finally, it seems to me this could be done using database queries, much simpler. Input, comments and suggestions welcomed. Philippe
