I've posted the indexing part,but I don't use this in my app.After I
create the index,I put that in a folder like /home/marco/RDFIndexLucece
and when I run the query I'm only searching (and not indexing).
String[] fieldsearch = new String[] {"name", "synonyms", "propIn"};
//RDFinder rdfind = new RDFinder("RDFIndexLucene/",fieldsearch);
TreeMap<Integer, ArrayList<String>> paths;
try {
this.paths = this.rdfind.Search(text, "path");
} catch (ParseException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
