Michael McCandless commented on LUCENE-7404:
--------------------------------------------
Can't you use the expressions module with function queries to get close to this?
> prepared query for introducing evaluation expression in query (not fixed
> second comparation member)

> Issue Type: Improvement
> Reporter: Cristian Lorenzetto

> Lucene is very powerfull but has a limitation very important. It is
> impossible to use when you want create a query where is a expression inside.
> field1: >= field2 where field1 and field2 is not possible.
> field1:= field2^2 -4 *field3
> it is pratically impossible to index statically document for this query but
> it is possible to do 2 things:
> 1) create a third field hidden here is saved the result.
> 2) when you use a prepared query , it is saved automatically in a different
> writer this info that you can save.
> Creating a prepared query lucene do all automatically for making this query
> using indexes.
> PS. Pay attention that fields in expression could be not only inside the
> current document but also in different documents/readers.
> It could be used also for join different document types(it is a subcase of
> the above problem).
