I have tested a search engine,PhpDig.
That is quite good.
It has a spider and search page.
Moreover, it supports templates.
It got most of functions I need.
But , at this stage , it is not able spider chinese web sites.
Perviously, I have faced a serious of permission problems during the uploading files.
I am 100% sure that I have changed everything to 777.
Well, I finally found out SELinux stop Apache to change the file system.
Then I turned SELinux off.
Everything are working fine.
