Subject Re: solr question

hey thanks for this info.  So I've got it almost to where I want my search
to be :)  I've changed my schema and solrconfig in the following ways:

in my schema I have 5 fields 2 of which are first-name and last-name.  I
have the text field and I copy last-name and first-name into it so that by
default I only search across those 2 fields.  What I did also is changed my
dismax request handler to the following:

 <requestHandler name="dismax" class="solr.DisMaxRequestHandler" >
    <lst name="defaults">
     <str name="echoParams">explicit</str>
     <float name="tie">0.01</float>
     <str name="qf">
        last-name^2.0 first-name^1.0
     </str>
     <str name="pf">
        last-name^2.0 first-name^1.0
     </str>
     <str name="fl">
        *,score
     </str>
    </lst>
  </requestHandler>

So that I boost last-name.

and to my query I add 3 sort params "score desc,last-name asc,first-name
asc".  This gives me nice results.  The only thing that is missing right now
is that wildcards do not work.  So if my q is john barber I get back the
correct doc.  When I change q to john bar* I don't get anything.  My text
field is defined as the default schema has it:

<fieldtype name="text" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="
stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory" protected="
protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="
stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="0"
catenateNumbers="0" catenateAll="0"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory" protected="
protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
    </fieldtype>

I would like to be able to support such wildcards


thanks a lot
