adjust search criteria for japanese/chinese

[smeddy]

currently searches must be 3 characters or more long to be accepted. that is fine in english, but it doesnt work in japanese/chinese.

in japanese/chinese a single chinese character can represent a word (i.e. "book" is represented in one word). most words, 90% or more, are represented with one or two characters.

by forcing people to use three characters or more--regardless of the language--you are basically making keyword searches in japanese/chinese languages if not impossible, then at least making them much less effective.

any way to rectify this?
