Hibernate Search 6 : Cannot use 'predicate:simple-query-string' on field

[yrodiere]

@yrodiere

The difference with Hibernate Search 5 is that Date field used to be indexed as strings, while they are now indexed as numbers in Hibernate Search 6.

Actually, that’s wrong:

1. The change of encoding I mentioned is wrong: dates are indexed as numbers in the Lucene backend, and already were in Hibernate Search 5. But you’re using the Elasticsearch backend, so this change of format is not relevant to you anyway; dates are indexed as date in the Elasticsearch backend, in Hibernate Search 5 and 6 both.
2. Taking into account the encoding used for dates in Hibernate Search 5, I don’t think simpleQueryString worked on date fields in Hibernate Search 5. Most likely, Hibernate Search 5 simply ignored these fields, and consequently simpleQueryString didn’t work for these fields.

Anyway, my advice still holds:

@yrodiere

If you want to use this predicate on this field, you need to change the type of the field, and that will probably require a custom value bridge

But alternatively, you can just remove this field from this predicate, since it was most likely ignored in Hibernate Search 5 anyway.
