@NumericField and NumericRangeQuery

Hello.
I repost here this question I posted at http://stackoverflow.com/questions/1122 ... defined-wi

I use hibernate search 4.1.0 with good results except for this problem. I´m trying to perform a range search in a column defined:

Code:

@Field(name = "startTime", store = Store.YES)
@NumericField
public Float startTime;

I have stored an item with startTime = 0.0f;

then I try to perform a range query:

Code:

NumericRangeQuery<Float> rangeQuery = NumericRangeQuery.newFloatRange(
                "startDate", -100000.0f, +100000.0f, true, true);
FullTextQuery fullTextQuery = fullTextEntityManager
                .createFullTextQuery(rangeQuery, Item.class);
results = fullTextQuery.getResultList();

First: I have no results.

Second: Inspecting the index with lukeall, I see simply stored what seems to be the toString() [judging by other experiments too], which looks not normal...

I feel like I´m missing something, any help would be appreciated. Thanks

Hi Pitagoras,
on the first issue, I think you're targeting the wrong field name; the field is "startTime", not "startDate". Unfortunately Lucene has no schema so it's hard to detect such an error over an intentional exotic mapping.

on second: what you see in Luke is the result of Store.YES

Wow! this is so embarrassing! Thanks for pointing it out!
Now it´s working fine!
Thank you.

n.p. you're welcome! It's hard to spot such problems ;-)

You actually got me thinking if & how we could detect such an issue, but I'm afraid that's not possible when wrapping a Lucene Query directly. If you where using the DSL (The QueryBuilder) it should throw a runtime exception about the field not being known.
