      public class ComplexPhraseQueryParser
      extends QueryParser

  QueryParser which permits complex phrase query syntax eg "(john jon jonathan~) peters*".

  Performs potentially multiple passes over Query text to parse any nested logic in PhraseQueries. - First pass takes any PhraseQuery content between quotes and stores for subsequent pass. All other query content is parsed as normal - Second pass parses any stored PhraseQuery content, checking all embedded clauses are referring to the same field and therefore can be rewritten as Span queries. All PhraseQuery clauses are expressed as ComplexPhraseQuery objects

  This could arguably be done in one pass using a new QueryParser but here I am working within the constraints of the existing parser as a base class. This currently simply feeds all phrase content through an analyzer to select phrase terms - any "special" syntax such as * ~ * etc are not given special status

- - ### Constructor Detail

    - #### ComplexPhraseQueryParser

          public ComplexPhraseQueryParser(Version matchVersion,
                                  String f,
                                  Analyzer a)

  - ### Method Detail

    - #### getFieldQuery

          protected Query getFieldQuery(String field,
                            String queryText,
                            int slop)

      Description copied from class: `QueryParserBase`
      Base implementation delegates to `QueryParserBase.getFieldQuery(String,String,boolean)`. This method may be overridden, for example, to return a SpanNearQuery instead of a PhraseQuery.
      Overrides:
        `getFieldQuery` in class `QueryParserBase`

    - #### parse

          public Query parse(String query)
                      throws ParseException

      Description copied from class: `QueryParserBase`
      Parses a query string, returning a `Query`.
      Overrides:
        `parse` in class `QueryParserBase`
      Parameters:
        `query` - the query string to be parsed.
      Throws:
        `ParseException` - if the parsing fails

    - #### newTermQuery

          protected Query newTermQuery(Term term)

      Description copied from class: `QueryParserBase`
      Builds a new TermQuery instance
      Overrides:
        `newTermQuery` in class `QueryParserBase`
      Parameters:
        `term` - term
      Returns:
        new TermQuery instance

    - #### getWildcardQuery

          protected Query getWildcardQuery(String field,
                               String termStr)
                                    throws ParseException

      Description copied from class: `QueryParserBase`
      Factory method for generating a query. Called when parser parses an input term token that contains one or more wildcard characters (? and *), but is not a prefix term token (one that has just a single * character at the end)

      Depending on settings, prefix term may be lower-cased automatically. It will not go through the default Analyzer, however, since normal Analyzers are unlikely to work properly with wildcard templates.

      Can be overridden by extending classes, to provide custom handling for wildcard queries, which may be necessary due to missing analyzer calls.

      Overrides:
        `getWildcardQuery` in class `QueryParserBase`
      Parameters:
        `field` - Name of the field query will use.
        `termStr` - Term token that contains one or more wild card characters (? or *), but is not simple prefix term
      Returns:
        Resulting `Query` built for the term
      Throws:
        `ParseException` - throw in overridden method to disallow

    - #### getRangeQuery

          protected Query getRangeQuery(String field,
                            String part1,
                            String part2,
                            boolean startInclusive,
                            boolean endInclusive)
                                 throws ParseException

      Overrides:
        `getRangeQuery` in class `QueryParserBase`
      Throws:
        `ParseException`

    - #### newRangeQuery

          protected Query newRangeQuery(String field,
                            String part1,
                            String part2,
                            boolean startInclusive,
                            boolean endInclusive)

      Description copied from class: `QueryParserBase`
      Builds a new `TermRangeQuery` instance
      Overrides:
        `newRangeQuery` in class `QueryParserBase`
      Parameters:
        `field` - Field
        `part1` - min
        `part2` - max
        `startInclusive` - true if the start of the range is inclusive
        `endInclusive` - true if the end of the range is inclusive
      Returns:
        new `TermRangeQuery` instance

    - #### getFuzzyQuery

          protected Query getFuzzyQuery(String field,
                            String termStr,
                            float minSimilarity)
                                 throws ParseException

      Description copied from class: `QueryParserBase`
      Factory method for generating a query (similar to `QueryParserBase.getWildcardQuery(java.lang.String, java.lang.String)`). Called when parser parses an input term token that has the fuzzy suffix (~) appended.
      Overrides:
