Method Detail

• setPositionIncrementGap

  public void setPositionIncrementGap(int gap)

• getPositionIncrementGap

  public int getPositionIncrementGap(String fieldName)

  Description copied from class: Analyzer
  Invoked before indexing a IndexableField instance if terms have already been added to that field. This allows custom analyzers to place an automatic position increment gap between IndexbleField instances using the same field name. The default value position increment gap is 0. With a 0 position increment gap and the typical default token position increment of 1, all terms in a field, including across IndexableField instances, are in successive positions, allowing exact PhraseQuery matches, for instance, across IndexableField instance boundaries.

  Overrides:

  getPositionIncrementGap in class Analyzer

  Parameters:

  fieldName - IndexableField name being indexed.

  Returns:

  position increment gap, added to the next token emitted from Analyzer.tokenStream(String,Reader). This value must be >= 0.

• initReader

  protected Reader initReader(String fieldName,
                              Reader reader)

  Description copied from class: Analyzer
  Override this if you want to add a CharFilter chain.

  The default implementation returns reader unchanged.

  Overrides:

  initReader in class Analyzer

  Parameters:

  fieldName - IndexableField name being indexed

  reader - original Reader

  Returns:

  reader, optionally decorated with CharFilter(s)
