Um, maybe. What I meant was to search for
any date, and see if it's in the desired range. It sounds like you
might be thinking (a) create a list of all eligible dates, then (b) for each date, search for that date in the log file. That sounds pretty inefficient I think. If you've got a 1-year range and a 1-MB log file to search, I wouldn't want to search it 365 times for different strings. But I guess it would be best to continue this
here so as not to fragment this discussion unnecessarily.
