Problem with word separators?

[Carsten Klement]

Hello,

 

I think I have a problem with configured Word separators.

 

For example, I would like 3 items to be found when searching for 640, 640-0 and 
two when searching for 640-01.

 

#1

artikelnummer_txt:"640*" AND  lng:"de"

    "docs":[{

      "artikelnummer_txt":"640-01"

    },{

      "artikelnummer_txt":"640-02"

    },{

      "artikelnummer_txt":"640-01LFM"

    }]

This is perfect, everything from the “artikelnummer_txt”  field that starts 
with 640 will be found.

 

#2 

artikelnummer_txt:"640-0*" AND  lng:"de"

"docs":[ ]

 

However, if I enter a "-" with a "0", no article is found. Here I expect all 
three items

 

#3

artikelnummer_txt:"640-01*" AND  lng:"de"

    "docs":[{

      "artikelnummer_txt":"640-01"

    }]

 

Here I only get one item, but I also expect two items.

 

My configuration in schema.xml

<dynamicField name="*_txt"  type="text_general"    indexed="true"  
stored="true"/>

  <fieldType name="text_general" class="solr.TextField" 
positionIncrementGap="100" multiValued="false">

    <analyzer type="index">

      <tokenizer name="standard"/>

      <filter ignoreCase="true" words="stopwords.txt" name="stop"/>

      <filter name="lowercase"/>

    </analyzer>

    <analyzer type="query">

      <tokenizer name="standard"/>

      <!-- Test START -->

      <filter name="wordDelimiterGraph" types="wordDelimiters.txt"/>

      <filter name="flattenGraph"/>

      <!-- Test ENDE -->

      <filter ignoreCase="true" words="stopwords.txt" name="stop"/>

      <filter ignoreCase="true" synonyms="synonyms.txt" name="synonymGraph" 
expand="true"/>

      <filter name="lowercase"/>

    </analyzer>

  </fieldType>

 

### wordDelimiters.txt

# Don't split numbers at '$', '.' or ','

$ => DIGIT

. => DIGIT

- => ALPHANUM 

 

Maybe someone has an idea what I'm doing wrong?

Thanks

Carsten
