How many is a lot? If it were 100 or so I would still be tempted to do
all 4,950 comparisons and find some sensible way to store

Can't say I've ever missed it, and haven't noticed others asking for
it. You need to remember that lucene is not a database.

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.

Bear in mind, I need a dynamic way of accomplishing this comparison.
In my case
