-------------------------------------------------------------
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.
