I am surprised by the results I am getting from a search in a Solr 3.4 index.
My schema has a multivalued field of type 'string' : <field name="qua_code" type="string" multiValued="true" indexed="true" stored="true"/> The field values are 7-digit or 9-digit integer numbers; this corresponds to a hierarchy. I could have used a numeric type instead of string but no numerical operations are performed against the values. Now, each document contains 0-N values for this field, such as: 8625774 1234567 123456701 123456702 123456703 9384738 When I make a search on facet.qua_code=1234567 , I am getting the counts I expect (seemingly correct) + a large number of counts for *other* field values (e.g. 9384738). If I reword the query as 'facet.query=qua_code:1234567 TO 1234567', I only get the expected counts. I can also filter out the extraneous results with a facet.prefix clause. Should I file an issue or am I misunderstanding something about faceting on multivalued fields ? Thanks.
