Thanks. I'll have to read up about it. I have a lot of comparisons to
make, so cannot precompute the values.
Don't you think this would be a nice feature for Lucene?
The Lucene query syntax has not changed much over the past few years.
Are there any plans to broaden its capabilities?

I guess you could do it in a custom Collector. They get passed
readers and docids so you could do the lookups and comparison. There
will be performance implications that you may be able to minimise via
FieldCache.
Storing the result in the index sounds much more sensible.

Hi Everyone
I have a problem where I need to compare two indexed fields as part of a
query.
For instance: modified_date[1970 to 2012] AND NOT deleted_date>modified_date
how would one implement this using Lucene?
Bear in mind, I need a dynamic way of accomplishing this comparison.
In my case, it is not possible to store the result of
deleted_date>modified_date at the time of indexing.
Thanks
Jamie
