lowercase text/strings to be used in list box

[Ben Incani <be...@datacomit.com.au>]

I have a field which will only contain several values (that include
spaces).

I want to display a list box with all possible values by browsing the
lucene terms.

I have setup a field in the schema.xml file.

    <fieldtype name="text_lc" class="solr.TextField">
      <analyzer>
        <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldtype>

I also tried;

    <fieldtype name="string_lc" class="solr.StrField">
      <analyzer>
        <tokenizer class="solr.LowerCaseTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldtype>


This allows me to browse all the values no problem, but when it comes to
search the documents I have to use the lucene
org.apache.lucene.analysis.KeywordAnalyzer, when I would rather use the
org.apache.lucene.analysis.standard.StandardAnalyzer and the power of
the default query parser to perform a phrase query such as my_field:(the
value) or my_field:"the value", which don't work?

So is there a way to prevent tokenisation of a field using the
StandardAnalyzer, without implementing your own TokenizerFactory?

sorry - this should have been posted on the Lucene user list.

...the solution is to use the lucene PerFieldAnalyzerWrapper and add the
field with the KeywordAnalyzer then pass the PerFieldAnalyzerWrapper to
the QueryParser.
