- - ### Method Detail

    - #### setLowercaseExpandedTerms

          void setLowercaseExpandedTerms(boolean lowercaseExpandedTerms)

      Set to `true` to allow leading wildcard characters.

      When set, `*` or `?` are allowed as the first character of a PrefixQuery and WildcardQuery. Note that this can produce very slow queries on big indexes.

      Default: false.

    - #### getLowercaseExpandedTerms

          boolean getLowercaseExpandedTerms()

      See Also:
        `setLowercaseExpandedTerms(boolean)`

    - #### setAllowLeadingWildcard

          void setAllowLeadingWildcard(boolean allowLeadingWildcard)

      Set to `true` to allow leading wildcard characters.

      When set, `*` or `?` are allowed as the first character of a PrefixQuery and WildcardQuery. Note that this can produce very slow queries on big indexes.

      Default: false.

    - #### setEnablePositionIncrements

          void setEnablePositionIncrements(boolean enabled)

      Set to `true` to enable position increments in result query.

      When set, result phrase and multi-phrase queries will be aware of position increments. Useful when e.g. a StopFilter increases the position increment of the token that follows an omitted token.

      Default: false.

    - #### getEnablePositionIncrements

          boolean getEnablePositionIncrements()

      See Also:
        `setEnablePositionIncrements(boolean)`

    - #### setMultiTermRewriteMethod

          void setMultiTermRewriteMethod(MultiTermQuery.RewriteMethod method)

      By default, it uses `MultiTermQuery.CONSTANT_SCORE_AUTO_REWRITE_DEFAULT` when creating a prefix, wildcard and range queries. This implementation is generally preferable because it a) Runs faster b) Does not have the scarcity of terms unduly influence score c) avoids any `TooManyListenersException` exception. However, if your application really needs to use the old-fashioned boolean queries expansion rewriting and the above points are not relevant then use this change the rewrite method.

    - #### getMultiTermRewriteMethod

          MultiTermQuery.RewriteMethod getMultiTermRewriteMethod()

      See Also:
        `setMultiTermRewriteMethod(org.apache.lucene.search.MultiTermQuery.RewriteMethod)`

    - #### setFuzzyPrefixLength

          void setFuzzyPrefixLength(int fuzzyPrefixLength)

      Set the prefix length for fuzzy queries. Default is 0.
      Parameters:
        `fuzzyPrefixLength` - The fuzzyPrefixLength to set.

    - #### setLocale

          void setLocale(Locale locale)

      Set locale used by date range parsing.

    - #### getLocale

          Locale getLocale()

      Returns current locale, allowing access by subclasses.

    - #### setTimeZone

          void setTimeZone(TimeZone timeZone)

    - #### getTimeZone

          TimeZone getTimeZone()

    - #### setPhraseSlop

          void setPhraseSlop(int defaultPhraseSlop)

      Sets the default slop for phrases. If zero, then exact phrase matches are required. Default value is zero.

    - #### getAnalyzer

          Analyzer getAnalyzer()

    - #### getAllowLeadingWildcard

          boolean getAllowLeadingWildcard()

      See Also:
        `setAllowLeadingWildcard(boolean)`

    - #### getFuzzyMinSim

          float getFuzzyMinSim()

      Get the minimal similarity for fuzzy queries.

    - #### getFuzzyPrefixLength

          int getFuzzyPrefixLength()

      Get the prefix length for fuzzy queries.
      Returns:
        Returns the fuzzyPrefixLength.

    - #### getPhraseSlop

          int getPhraseSlop()

      Gets the default slop for phrases.

    - #### setFuzzyMinSim

          void setFuzzyMinSim(float fuzzyMinSim)

      Set the minimum similarity for fuzzy queries. Default is defined on `FuzzyQuery.defaultMinSimilarity`.

    - #### setDateResolution

          void setDateResolution(DateTools.Resolution dateResolution)

      Sets the default `DateTools.Resolution` used for certain field when no `DateTools.Resolution` is defined for this field.
      Parameters:
        `dateResolution` - the default `DateTools.Resolution`
