Subject [jira] [Commented] (SOLR-3293) Request Handler inheritance
Date Thu, 29 Mar 2012 17:22:27 GMT


Jan Høydahl commented on SOLR-3293:

My thought was a super-simple approach. A RequestHandler with an {{extends}} would be initialized
with a NamedList being the sum of the parent and the sub. For this to work, the parsing of
<requestHandler> tags in solrconfig.xml would necessarily need to be done in correct
order... Should we allow any number of levels or only one?

> It would be useful if one Solr request handler could inherit from another.  Or perhaps
a mixin style so multiple could be merged in.  I've wanted to do this to reduce repeating
myself in solrconfig.xml RH configurations.  Maybe all that's needed is one RH which provides
the defaults to all the other search handlers.  This feature could also be useful for establishing
some defaults like for "df" and "q.op" and "f.myfieldname.facet.method".
