Build a compound query

[Will Liang]

I am trying to build the following query using SolrNet.

(type:Contact) AND ((firstName:Jason)^100) OR ((lastName: Winters)^100)
 

I have tried to use the following code:

var query = new SolrQuery("type:Contact") &&
            new SolrQuery("firstName:Jason").Boost(100) ||
            new SolrQuery("lastName:Winters").Boost(100); 

Looking at the Catalina log in Tomcat, the following query was produced, the nested brackets is not what I expected, is this correct?

q=((type:Contact+AND+(firstName:Jason)^100)+OR+(lastName:Winters)^100)
 

Also, it would be perfect if I can embed this search logic using a request handler in Solr configuration, does anyone know how to do it?

Just as you used parentheses to group both terms involved in the OR expression, you need to use parentheses in the SolrNet expression.

As in most languages, && has a higher precedence than ||.

As far as I know you can only set fixed parameters in Solr configuration. Look up "defaults", "appends", "invariants" in the sample Solr config: http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/example/solr/conf/solrconfig.xml

Cheers,

Mauricio
