This isn't really a good use case for an index like Lucene. The most essential property of an index is that it lets you look up documents very quickly based on *precomputed* values.

Hi all,

I'm looking for a way to use multi-values in a filter.

I want to be able to search on sum(field)=100, where field has values in one documents:

field=60 field=40

In this case 'field' is a LongField. I examined the code in the FieldCache, but that seems to focus on single-valued fields only, or

It this something that can be done in Lucene? And what would be a good approach?

Thanks in advance,
