Problem with Synonyms

Hello,

this is my first time writing at this mailing lost, so hello everyone.

I am having issues with synonyms.

I added the synonym to one of my field types:

|<fieldType  name="text_general"  class="solr.TextField"  positionIncrementGap="100">
       <analyzer  type="index">
         <tokenizer  class="solr.StandardTokenizerFactory"/>
         <filter  class="solr.StopFilterFactory"  ignoreCase="true"  words="stopwords.txt"  enablePositionIncrements="true"/>
         <filter  class="solr.LowerCaseFilterFactory"/>
         <filter  class="solr.SynonymFilterFactory"  synonyms="synonyms.txt"  ignoreCase="true"  expand="true"/>
         <filter  class="solr.NGramFilterFactory"  minGramSize="1"  maxGramSize="15"/>
       </analyzer>
       <analyzer  type="query">
         <tokenizer  class="solr.StandardTokenizerFactory"/>
         <filter  class="solr.StopFilterFactory"  ignoreCase="true"  words="stopwords.txt"  enablePositionIncrements="true"/>
         <filter  class="solr.LowerCaseFilterFactory"/>
       </analyzer>
     </fieldType>


I also added some Synonyms to my Synonyms.txt which is in the conf folder of my core.

However, when i look into the analyzer, the content wont be replaced and I cant figure out where the problem lies.

Can anybody help here? Im totally stuck...

The SF part is in the analysis page but nothing is substituted.

I reloaded, removed and readded the core, reindexed....nothing worked :(

I wonder if the SF actually uses the correct file for synonyms. I have 
it laying in the conf folder of the core. Is that correct?

Please explain exactly what "but nothing
really happens" means. Do you mean that
you see the SF in the analysis page but there
are no substitutions? Or you don't get
search results? Or???

You have to reload the core after making changes
at minimum, you can restart the Solr instance
if you're paranoid. And you have to re-index
for changes in the index part of the analysis
chain to take effect.

Erick

Yeah thats the thing.

It applies the Synonym Filter, but nothing really happens.

Is there a way to see if the SF load my Synonym file?

SOLR has a nice analysis page. You can use it to get insight what is
happening after each filter is applied at index/search time
