Why do you say at the indexing part:
The given search term is: *X-002-99-495*
WordDelimiterFilterFactory indexes the following word parts:
* X (shouldn't be there)
* 00299495 (shouldn't be there)
??
You've set catenateNumbers="1" in your fieldType for the indexig part,
so WDFF is doing exactly what it should... smushing all the numbers it
separated into a single entity.
And the whole _point_ of WDFF is to split on "non alpha nums" and
index the parts it splits.
This seems like it's behaving exactly as it should.
Or I'm missing something totally.
Best,
