Hi Rok, If I understood the use case rightly, Grouping of the results are possible in Solr http://wiki.apache.org/solr/FieldCollapsing Probably, you can create new fields with the combination for the groups and use the field collapsing feature to group the results.
Id Type1 Type2 Title Group1 1 a b xfg ab 2 a c abd ac 3 a d thm ad 4 b a efd ba 5 b b ikj bb 6 b c azd bc It also provides the sort and a group sorting features.
