Searched for Cement, Got LED Bulbs Instead

Full text search in English usually splits text into whole words so this doesn't happen.

I was told that in CJK languages you can't define a clear segmentation for words and it is more common to match exact substrings. I was playing a Chinese gatcha game the other day and noticed it was efficient to search for 'k s' when looking for 'pink storm' since the last letter of one word and the first letter of the next word are more evenly distributed than two adjacent letters in a word (e.g. Searching for 'st' would be a disaster.)
