Hoss Man commented on SOLR-109:
-------------------------------

> The only part that I did not understood is the
> handlers part. 

> I did a grep for SolrQueryParser but could not find an example where I can call
> SolrQueryParser.setParams(SolrParams params) to prepare the substitution
> (setSubstitutionSolrParam(String queryText){}).

i think StandardRequestHandler currently uses a static parseQuery method from QueryParsing ... i've never really been fond of that, it should be replaced with a factory method that returns a SolrQueryParser, then the handler could set whatever options it wants.

there's definitely an instance of SolrQueryParser in DisMax handler ... used to parse the boost queries and optional alt.q.

> Allowing variable substitution in the lucene query params seems pretty slick 
> ... a more general solution might be to modify the SolrQueryParser
> directly to have a new "void setParamVariables(SolrParams p)" method.
