public interface CommonQueryParserConfiguration
Configuration options common across queryparser implementations.

  • Method Details

    • 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()

    • setMultiTermRewriteMethod

      void setMultiTermRewriteMethod(MultiTermQuery.RewriteMethod method)
      By default, it uses MultiTermQuery.CONSTANT_SCORE_REWRITE 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.

      MultiTermQuery.RewriteMethod getMultiTermRewriteMethod()

    • 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:

    • 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.defaultMaxEdits.

    • 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
