Searching - Why is there a 3-character min length?

[Skabana159]

The problem is that the Delphi search engine will match even parts of words, for example, if you were to search for DOG, you would get a hit for boonDOGgle. Once you get to shorter combinations of letters, it is much more common to get false hits. Try searching for "multiplier" or something like that. What use is searching for "2x" if you don't be more specific anyway? What do you want to know about "2x?" Doubtless, you can think of a way to be more specific in your search.
