Re: Reverse range search
Hi, I think I have seen a comment on the list from someone with the same need a few months ago. He planned to make a new fieldType to support this, e.g. MinMaxRangeFieldType which would be a polyField type holding both a min and max value, and then you could query it q=myminmaxfield:123 I did not find it as a Jira issue however, but I can see how it would be useful for a lot of usecases. Perhaps you can create a Jira issue for it and supply a patch? :) -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com On 28. okt. 2010, at 23.24, kenf_nc wrote: Doing a range search is straightforward.

Re: Reverse range search
I wonder if function queries might help you here (be aware that these aren't my strong point though).

Reverse range search
Doing a range search is straightforward. I have a fixed value in a document field, I search on [x TO y] and if the fixed value is in the range requested it gets a hit.
