How to query solr with + (required) match using solrnet

I'm using solrnet library for the interaction with solr. Is there a method in solrnet that formats a required query. I have seen the NotQuery which renders a - (not) in the query, but I now have a need for the + (required) in the query.

Is this possible using solrnet?

I've tried to implement a RequiredQuery and RequiredQuerySerializer similar to NotQuery, but I can't get it injected into the solrnet pipeline. (I know I can modify the SolrNet sourcecode, but I'd really like to keep the solrnet binary unmodified.)

Solution

  • The easiest way is to have RequiredQuery implement ISelfSerializingQuery (example).

    A separate serializer is used for more complex cases, or to keep things neater. When using a separate ISolrQuerySerializer, register in your IoC container an AggregateQuerySerializer that includes both your serializer and the DefaultQuerySerializer.
