     *     Typically pulled from this manager.
     * @param searchFilter Filter to use to perform the search.  Typically pulled from this manager.
     * @param startIndex Number/index of first result to include in results.  (-1 for no limit)

     * @param suffixToTrim An arbitrary string to trim from the end of every attribute returned.  null to disable.
