Yes. See http://wiki.apache.org/solr/SolrQuerySyntax - The standard Solr Query Parser syntax is a superset of the Lucene Query Parser syntax. Which links to http://lucene.apache.org/core/3_6_0/queryparsersyntax.html
Note - Based on the info on these pages I believe the "+" symbol is to be placed just before the mandatory value, not before the field name in the query.

I just have to add a "+" symbol in front of the mandatory parameter, like: +myField:my value I was wondering if there was something similar in Solr queries? Or is this behaviour activated by default?
