Hi Mike, my first description wasn't very exact. Actually these are two different cases, which occur not together. One time I need a search with "begins" and another time with "contains". And I decided to stay with such a standard repeat loop thru the array, without extracting the keys before or using any extra commands like filter. Thanks for caring Tiemo

Did some testing out of curiosity, and WOW this is fast. repeat for each key tKey in tArray if tArray[tKey] begins with tSearchString or \ tArray[tKey] contains tSearchString then put tKey & return after tResults end if end repeat The only question I have is.. why search for the same thing twice? If it "contains" it also "begins with" so its a redundant check. (making it faster) Am I missing something here?
