-------------------------------------------------------------

I have a patch that adds the ability to configure a text analyzer on a text field.  There is support for three kinds of analyzer, SimpleAnalyzer, KeywordAnalyzer and StandardAnalyzer with an option list of stop words.

To configure, for example a standard analyzer with a stop word list:
{noformat}
 text:map (
         [ text:field "text" ; 
           text:predicate rdfs:label;
           text:analyzer [
               a  lucene:StandardAnalyzer ;
               text:stopWords ("foo" "bar" "baz") # optional
           ]
         ]
{noformat}
The property {{text:analyzer}} specifies the analyzer for a field. The value of that property is a node representing the analyzer.  That nodes has an rdf:type property specifying the type of the analyzer.  Other properties may specify other configuration options.

> The specific request is to be able to specify that a field should by analysed using Lucene's KeywordAnalyzer, though it is obvious that may generalized to specifying any analyzer.
