Ickle purely negative fulltext subqueries cause empty results
-------------------------------------------------------------
Key: ISPN-7982
URL:
https://issues.jboss.org/browse/ISPN-7982
Project: Infinispan
Issue Type: Bug
Components: Embedded Querying
Affects Versions: 9.0.0.Final
Reporter: Gustavo Fernandes
Assignee: Adrian Nistor
Fix For: 9.4.0.Final
When using parethesis in an Ickle full text predicate, it can generate subqueries that
are pure negative, e.g.
{{from IspnEvent where (tags : ('tagA' and (not 'a0')))}}
In Lucene, the query
{{+tags:taga +(-tags:a0)}}
is different from
{{+tags:taga -tags:a0}}
The latter works as expected, but the former brings empty results since Lucene does no
support purely negative subqueries. In order for the former query to work, it needs to add
all documents as another term to the subquery, for e.g. {{+tags:taga +(\*:\* -tags:a0)}}.
