• If you are trying to use Boolean operators, they must be ALL CAPS: (((garcher OR researches) OR ((lsearches OR larch) OR ((searches OR search) OR semarches))) OR arches)*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((garcher or researches) or ((lsearches or larch) or ((searches OR search) or semarches))) or arches)*".
