Hi, I have encoutered a problem applying StopFilterFactory and SynonimFilterFactory. The problem is that SynonymFilter removes the gaps that were previously put by the StopFilterFactory. I'm applying filters in query time, because users need to change synonym lists frequently.
This is my schema, and an example of the issue: String: "documentacion para agentes" org.apache.solr.analysis.WhitespaceTokenizerFactory {luceneMatchVersion=LUCENE_35} position 1 2 3 term text documentación para agentes startOffset 0 14 19 endOffset 13 18 26 org.apache.solr.analysis.LowerCaseFilterFactory {luceneMatchVersion=LUCENE_35} position 1 2 3 term text documentación para agentes startOffset 0 14 19 endOffset 13 18 26 org.apache.solr.analysis.StopFilterFactory {words=stopwords_intranet.txt, ignoreCase=true, enablePositionIncrements=true, luceneMatchVersion=LUCENE_35} position 1 3 term text documentación agentes startOffset 0 19 endOffset 13 26 org.apache.solr.analysis.SynonymFilterFactory {synonyms=sinonimos_intranet.txt, expand=true, ignoreCase=true, luceneMatchVersion=LUCENE_35} position 1 2 term text documentación agente archivo agentes type SYNONYM SYNONYM SYNONYM SYNONYM startOffset 0 19 0 19 endOffset 13 26 13 26 As you can see, the position should be 1 and 3, but SynonymFilter removes the gap and moves token from position 3 to 2 I've got the same problem with Solr 3.5 y 4.0. I don't know if it's a bug or an error with my configuration. In other schemas that I have worked with, I had always put the SynonymFilter previous to StopFilter, but in this I prefered using this order because of the big number of synonym that the list has (i.e. I don't want to generate a lot of synonyms for a word that I really wanted to remove).
