Serkan,
it's easier using the IndexReader class to get the information you need. If you just need the doc frequency of each term you could use the sample.
IndexReader ir = null;
try {
if (!IndexReader.indexExists("tmp/index"))
return;
ir = IndexReader.open("/tmp/index");
TermEnum termEnum = ir.terms();
while (termEnum.next()) {
Term t = termEnum.term();
System.out.println(t.text() + " --> " + ir.docFreq(t));
}
}
catch (IOException e) {
System.out.println(e.toString());
}
finally {
if (ir != null) {
try {
ir.close();
} catch (IOException e) {
System.err.println("IOException, opened IndexReader can't be closed: " + e.toString());
}
}
}
hope this helps, Bernhard

I want to build a list of terms of all documents and their frequency data. It seems the information I need is in "tis" and "tii" files. However I havent't found a way to handle them till now.
How can I get the term frequency data?
Thanks ,
Serkan
