I have a disjunctive Lucene query like this:
(clause_1 OR clause_2 OR ... OR clause_N) and I want to add an additive boost query on top of it, just like the bq parameter in DisMax parser.
I tried {!edismax qf='' bq='my_boost_query'}(clause_1 OR clause_2 OR ... OR clause_N) but it returned zero result. (I assume it might be caused by the empty qf parameter)
Is is possible to do it without rewriting my query using DisMax format? Perhaps some special syntax of Lucene query parser, like _val_ and such? Or may be DisMax wrapper does the job, but I am just missing something in the above query syntax?
