I'm indexing using my custom fieldbridge to enable the facet engine of the lucene 4.
In order to correctly add the SortedSetDocValue type documents, I need to obtain my custom analyzers. So is there any way to obtain the SearchFactory obejct?

I would like reach the SearchFactory object for calling the getAnalyzer method.

I solved my problem.
I created a singleton for the my CustomAnalyzer object. I get the value for the document using this utility function:
<code>
public static List<String> tokenizeString(Analyzer analyzer, String string) {
List<String> result = new ArrayList<String>();
try {
TokenStream stream = analyzer.tokenStream(null, new StringReader(string));
stream.reset();
while (stream.incrementToken()) {
result.add(stream.getAttribute(CharTermAttribute.class).toString());
}
stream.end();
stream.close();
} catch (IOException e) {
// not thrown b/c we're using a string reader...
throw new RuntimeException(e);
}
return result;
}
