Evgeny Tugarev updated OAK-9587:
--------------------------------
Description:
JCR Query which does not specify an INDEX() tag may eventually pick up the
tagged index.
This is not an error, however this behaviour is not always desirable when a
tagged index must only be used by a specific query which explicitly specify an
index tag and be transparent to other queries which does not specify it.
If I understand correctly the check is done
[here|https://github.com/apache/jackrabbit-oak/blob/db55659c08dff47e9c28eef03f1a5628af13d8b2/oak-search/src/main/java/org/apache/jackrabbit/oak/plugins/index/search/spi/query/FulltextIndexPlanner.java#L412]
I propose to add a boolean parameter (strictTagCheck or sth similar) which
enforces a strict check for the index tag - the idea is to mark such index as
wrong in case query does not specify the index tag and an index definition
contains a tag. I think this change is also a backward compatible as does not
change the existing behaviour, but adds a new one.
N.B. Currently a workaround applied to set a high costPerExecution and
costPerEntry in index definition has a negative side effect for the query
falling back to traverse and failing as it traversing > 100 000 nodes.
And, yes, it's an urgent issue :)
