It all depends on what you mean by an "operator".
Start by describing in more detail what problem you are trying to solve.
And how do you expect your users or applications to use this "operator".
Give some examples.
Solr and Lucene do not have "operators" per say, except in query parser
syntax, but that is hard-wired into the individual query parsers.

Subject: New operator.
Hi all, I want to add a new operator to my solr. I need that operator
to call my proprietary engine and build an answer vector to solr, in a way
that this vector will be part of the boolean query at the next step. How
do I do that?
Thanks
