When I migrate from Solr 1.4 to solr 3.1 , some errors occurred
I used sort on a text field which works in solr 1.4 to sort on this field
and in solr 1.4 I used an integer field in bf parameter but not worked in solr 3.1 with error message : can not use FieldCache on multivalued field
I need hellp to solve this problem especially I have to use this fields to boost my results
If you have these fields in your schema.xml as you should make sure they are set to multiValued=false
