             Summary: Can/should we store NumericField's precisionStep in the index?
                 Key: LUCENE-5069
                 URL: https://issues.apache.org/jira/browse/LUCENE-5069
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Michael McCandless


I was just helping a user (buzzkills) on IRC on why NumericRangeQuery was failing to hit the expected docs ... and it was because s/he had indexed with precStep=4 but searched with precStep=1.

Then we wondered if it'd be possible to somehow catch this, e.g. we could maybe store precStep in FieldInfo, and then fail at search time if you use a "non-matching" precStep?

I think you can index fine and then search on a multiple of that?  E.g., I can index with precStep=2 but search with precStep=8?  But indexing with precStep=4 and searching precStep=1 won't work ...
