Off the top of my head... assuming you have an IndexReader (or MultiReader)
called reader:
TermEnum te = reader.terms();
while (te.next()) {
Term currentTerm = te.term();
TermDocs docs = reader.termDocs(currentTerm);
int docCounter = 1;
while (docs.next()) {
System.out.println(currentTerm.text() + ", doc" + docCount + ",
" + docs.freq());
docCounter++;
}
}
