Hello Mike, Solr is too flat yet. Work is in progress https://issues.apache.org/jira/browse/SOLR-3076 Good introduction is in Michael's blog http://blog.mikemccandless.com/2012/01/searching-relational-content-with.htmlbut it's only about Lucene Queries. Colleague of my blogged about the same problem but solved it by an alternative approach http://blog.griddynamics.com/search/label/Solr Finally we give up with termspositions/spans and considering BJQ as a solution.
