| Xapian::TermIterator::TermIterator | ( | const TermIterator & | other | ) |
Copying is allowed.
The internals are reference counted, so copying is also cheap.

Assignment is allowed.
The internals are reference counted, so assignment is also cheap.

| Xapian::termcount Xapian::TermIterator::get_wdf | ( | ) | const |
Return the wdf of the current term (if meaningful).
The wdf (within document frequency) is the number of occurences of a term in a particular document.

| Xapian::doccount Xapian::TermIterator::get_termfreq | ( | ) | const |
Return the term frequency of the current term (if meaningful).
The term frequency is the number of documents which a term indexes.
