## Method Details

### intersect

public TermsEnum intersect(CompiledAutomaton compiled, BytesRef startTerm) throws IOException
Description copied from class: `Terms`
Returns a TermsEnum that iterates over all terms and documents that are accepted by the provided `CompiledAutomaton`. If the `startTerm` is provided then the returned enum will only return terms `> startTerm`, but you still must call next() first to get to the first term. Note that the provided `startTerm` must be accepted by the automaton.

This is an expert low-level API and will only work for `NORMAL` compiled automata. To handle any compiled automata you should instead use `CompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms)` instead.

NOTE: the returned TermsEnum cannot seek.

Overrides:
  `intersect` in class `Terms`
Throws:
  `IOException`

### iterator

public TermsEnum iterator() throws IOException
Description copied from class: `Terms`
Returns an iterator that will step through all terms. This method will not return null.

Overrides:
  `iterator` in class `FilterLeafReader.FilterTerms`
Throws:
  `IOException`

### getMin

public BytesRef getMin() throws IOException
Description copied from class: `Terms`
Returns the smallest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.

Overrides:
  `getMin` in class `Terms`
Throws:
  `IOException`

### getMax

public BytesRef getMax() throws IOException
Description copied from class: `Terms`
Returns the largest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.

Overrides:
  `getMax` in class `Terms`
Throws:
  `IOException`
