Subject Re: Extracting URLs while indexing
Date Wed, 20 Jan 2010 17:55:59 GMT
that is the field type:
    <fieldType name="body_text" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <!-- in this example, we will only use synonyms at query time
        <filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
        -->
        <!-- Case insensitive stop word removal.
          add enablePositionIncrements=true in both the index and query
          analyzers to leave a 'gap' for more accurate phrase queries.
        -->
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
<!--        <filter class="solr.LowerCaseFilterFactory"/> -->
<!--        <filter class="solr.SnowballPorterFilterFactory"
language="English" protected="protwords.txt"/> -->
        <filter
class="org.bogdan.solr.analysis.SnowballPorterWithUnstemLowerCaseFilterFactory"
language="English" protected="protwords.txt" unstemmed="unstemmed.txt"/>
      </analyzer>


and that is the field def:

<field name="msg_body" type="body_text" termVectors="true" indexed="true"
stored="true"/>
