I can't find any strings in the open office calc(version 3.2.1 in windows) document (*.xls) by doing a search(Ctrl+F).I tried with all options and then also i didn't get any positive result.
All suggestions are welcome!
I had this problem in Open Office Calc(*.ods)(version 4.0.1). The result when searching for a string I could clearly see was always "Search key not found". Solved when I realised I had ticked "entire cells"in "Find & Replace" for a particular purpose, and then forgotten to untick it.
