Created attachment 115449 [details] Simple example of MATCH function problem When doing an exact MATCH and the index/search has a plus sign (+) in the field. For example if you have list: a b c+ d and you do match with a "c+" it will not find it correctly. Try same thing in excel and no problem. See attach simple example.
Hi @skiani, thanks for reporting. Function works properly, the issue is that the file has activated regular expression for search. Menu/Tools/Options/LibreOffice calc/Calculate - Enable regular expressions in formula. Disable it so it must work fine. You can look about regular expressions in the inner help. '+' is part of the regular expression, if you want use regex then for search for '+' you need to disable their special meaning, with a backslash before it '\+'
