Created attachment 64571 [details] Test file Following the example from http://wiki.services.openoffice.org/wiki/Documentation/How_Tos/Regular_Expressions_in_Calc#Regular_expressions_in_Calc_functions I am getting a different result. Entering: =COUNTIF(cell , "text") actually becomes: =COUNTIF(cell , "^text$") So if a cell contains "123textABC" doing =COUNTIF(cell , "text") will not find a match, however it should. I have attached a test file which produces an error with a few cells.
Read again the link in your post : "Additionally if "Search criteria = and <> must apply to whole cells" is ***not*** selected then 'Fred', 'bride', and 'Ridge' will also be counted. " Please learn how to use a spreadsheet and if something goes wrong ask on user mailing list or forums before submit a bug report.
