Exact search for phrase "1/f"

I work on problem that involve “1/f” phrase in the database of articles, while the search mostly work in my document, the search for phrase “1/f” also find other phrases like “1(f” or “1 f” (mostly scanned books or fragment of diagram).

Is it possible to make it more exact?

No, this is not possible. It’s well known (and documented) DEVONthink doesn’t index but a very small, specific number of non-alphanumeric characters.


You could give this script a shot.

I think it should achieve what you’re trying to do.
