Phpcms Full Site Search Why not as many people do?

Phpcms Full Site Search Why not as many people do?
Online about phpcms A lot of full-text search, Baidu a big pile, but not a line, not to say that support Chinese or not, first say that support English bar
But no one can do, I wonder, these people do not try to finish after writing it? You say they do not try it seems unlikely, who finished not to try, after all, the last is to use. But the truth is really the opposite, incredible.
Full-Text search as implies is as long as the article has wanted to search the word, it shows you, that is, fuzzy matching, white is to use like to fuzzy matching.
But, the search engine in Phpcms really can't search
Just take this station, http://www.chengdeshixinxi.com/remould/23.html.
It also wrote a tutorial is full-text search, and this station is also used phpcms do, but you try, you can not find, really other people heinous, I hope this rotten text less the better, I think he does not blow is not dead, we think?!
------to solve the idea----------------------
Either like or full-text search (although the latter is much more efficient than the former)
First you have to divide the retrieved string into words, and the character set must match
