  • Method Details

    • preSearch

      public abstract SearchProcessorInfo preSearch(String query)
      This method is called before the search is performed. See SearchProcessorInfo for types of information that can be used by the search display. If a SearchProcessorInfo with an empty, non-null query ("") is returned, no search will be executed, resulting in no search results.
      Returns:
      SearchProcessorInfo, or null for no changes.
    • postSearch

      public abstract ISearchResult[] postSearch(String query, ISearchResult[] results)
      This method is called after the search is performed. This method can be used to return a modified result set. For example, one can change the result score of an item, add new results to the top of the list, or remove results. This method exists for backwards compatibility. Overwrite postSearch(String, String, ISearchResult[], String, IHelpResource[]) if more information like the locale, etc. is needed instead.
      Returns:
      The modified results, or null for no changes.
    • postSearch

      public ISearchResult[] postSearch(String query, String originalQuery, ISearchResult[] results, String locale, IHelpResource[] scopes)
      This method is called after the search is performed. This method can be used to return a modified result set. For example, one can change the result score of an item, add new results to the top of the list, or remove results.
      Parameters:
      query - The actually query that was executed (after any changes made by preSearch(String)).
      originalQuery - The original query before any changes made by preSearch(String).
      results - The results of the executed query.
      results - The locale.
      results - The set scopes (might be null).
      Returns:
      The modified results, or null for no changes.
