Subject RE: Question: searching on a NumericField, with sort and filter
Date Tue, 06 Jul 2010 18:31:03 GMT
Hi Eduardo,

For sorting or a NumericRangeQuery, the field must be *indexed*. Storing has
no effect at all, it's only needed, if you want to show the value in search
results. That is important for *any* type of field (not only NumericField).
