Hi,
This happens because your tokenizer will generate seperate tokens for `exercise dvds`, so the SynonymFilter will try to find declared synonyms for `exercise` and `dvds` separately. It's behavior is documented [1] on the wiki.

As an example I have the following synonym; exercise dvds => fitness When I search for exercise dvds I want to return all docs in the index which contain the keyword fitness. I've read the wiki about solr.SynonymFilterFactory which recommends expanding the synonym when indexing, but I'm not sure this is what I want as none of my documents have the keywords exercise dvds. Here is the field definition from my schema.xml; When I test my search with the analysis page on the admin console it seems to work fine; Query Analyzer org.apache.solr.analysis.WhitespaceTokenizerFactory {} term position 12 term text exercisedvds term type wordword source start,end 0,89,13 payload org.apache.solr.analysis.SynonymFilterFactory {ignoreCase=true, synonyms=synonyms.txt, expand=true} term position 1 term text fitness term type word source start,end 0,13 payload org.apache.solr.analysis.TrimFilterFactory {} term position 1 term text fitness term type word source start,end 0,13 payload org.apache.solr.analysis.StopFilterFactory {ignoreCase=true, enablePositionIncrements=true, words=stopwords.txt} term position 1 term text fitness term type word source start,end 0,13 payload org.apache.solr.analysis.LowerCaseFilterFactory {} term position 1 term text fitness term type word source start,end 0,13 payload org.apache.solr.analysis.SnowballPorterFilterFactory {language=English, protected=protwords.txt} term position 1 term text fit term type word source start,end 0,13 payload ...but when I perform the search it doesn't seem to use the SynonymFilterFactory; 0 0 exercise dvds 0 on standard 2.2 standard on *,score 10 ..... exercise dvds exercise dvds PRODUCTKEYWORDS:exercis PRODUCTKEYWORDS:dvds PRODUCTKEYWORDS:exercis PRODUCTKEYWORDS:dvds -- View this message in context: http://lucene.472066.n3.nabble.com/Multi-word-synomyms-tp1019722p1019722.html Sent from the Solr - User mailing list archive at Nabble.com.
