Examples of org.apache.lucene.index.TermDocs.skipTo()

org.apache.lucene.index.TermDocs.skipTo()
Skips entries to the first beyond the current whose document number is greater than or equal to target.
Returns true iff there is such an entry.
Behaves as if written:
```
 boolean skipTo(int target) { do { if (!next()) return false; } while (target > doc()); return true; } 
```
Some implementations are considerably more efficient than that.

            } while (!matchDoc(doc = termDocs.doc()));
            return doc;
          }
          
          public int advance(int target) throws IOException {
            if (!termDocs.skipTo(target))
              return doc = NO_MORE_DOCS;
            while (!matchDoc(doc = termDocs.doc())) { 
              if (!termDocs.next())
                return doc = NO_MORE_DOCS;
            }
