[MonetDB-users] tijah exact matching

Is there a way to force a tijah query to return only exact matches? For example, if I search for "wind farm", as in: ("tijah:queryall[about(., wind farm)]") I get matches for "wind farm", "wind" and "farm" but say I only want matches for "wind farm"? I can of course loop through the result with contains(., "wind farm") to exclude unwanted results but that has performance implications. -- Roy
