    • escapeSearchTerm

      public String escapeSearchTerm(String searchTerm, boolean ignoreBracket)
      This helper method escapes special characters found in a lucene search term. The method can be used by clients to prepare a search phrase.

      Special characters are characters that are part of the lucene query syntax

      + - Ungültige Eingabe: "&"Ungültige Eingabe: "&" || ! ( ) { } [ ] ^ " ~ * ? : \ /

      Clients should use the method normalizeSearchTerm() instead of escapeSearchTerm() to prepare a user input for a lucene search.

      Parameter:
      searchTerm -
      ignoreBracket - - if true brackes will not be escaped.
      Gibt zurück:
      escaped search term

    • normalizeSearchTerm

      public String normalizeSearchTerm(String searchTerm)
      This method normalizes a search term. The method can be used by clients to prepare a search phrase. The serach term will be lowercased and special characters will be replaced by a blank separator

      e.g. 'europe/berlin' will be normalized to 'europe berlin'

      In case the searchTerm contains numbers the method escapes special characters instead of replacing with a blank:

      e.g. 'r-555/333' will be converted into 'r\-555\/333'

      Special characters are characters that are part of the lucene query syntax
