: I am trying to write a util which can parse a Lucene/Solr query and convert : into an object representation to add more clauses to the query. : : Eg. : Input: (name:John AND name:Doe) : Output: ((firstName:John OR lastName:John) AND (firstName:John OR : lastName:John))
edismax can support this natively, no coding required -- although itwill build a DisjunctionMaxQuery across the "name"=>"firstName,lastName" expansion, not a simple BooleanQuery (but if you set the "tie" param to 1.0 it should be equivilent, although i suspect a DisjunctionMaxQuery with the default tie breaker value would fit your usecase better anyway)... http://wiki.apache.org/solr/ExtendedDisMax#Field_aliasing_.2BAC8_renaming So try something like this... http://localhost:8983/solr/select?defType=edismax&f.name.qf=firstName+lastName&q=%28name:John%20AND%20name:Doe%29&debugQuery=true -Hoss
