I am trying to use MATCH() and/or LOOKUP() in LibreOffice Calc. I have the "Search criteria = and <> must apply to whole cells" and the "Enable regular expressions in formulas" options selected. The item I am looking for is a multi word string.

How do I provide a search criteria as a cell reference (E3) in to LOOKUP(E3, B1:B20, C1:C20) and have it match the value in B1:B20 EXACTLY? Right now it is matching partial strings rather than matching the cell values exactly.
