Issue with numeric fields in 4.x
Hello,
I'm new to this list and a Lucene n00b so I'm hoping you all can help me.
I'm consuming an index that was built with version 4.7.2. The index has
numeric fields. When I try to search on those fields I get no result. I
opened the index up with Luke and it seems there is something weird going
on with those field. I can see that there are values in the fields but when
I try to access them it just show gibberish. Has anyone seen this before
and can maybe point me in the right direction to troubleshooting this
further? I'm including a screenshot of Luke that demonstrated what I'm
talking about.

Any help would be greatly appreciated as this has had me stuck for a while!

Okay, that makes sense.
Thanks!

Hi,
If you use NumericField you can only use NumericRangeQuery to search on them (also for single value query aka TermQuery). The same applies for Lucene 6s point fields. Most query parsers have no schema information, so they can only create Term* not Numeric* query types, unless you subclass them to have special handling for the fields without classical terms.
