Hi
   Here is my project:

1) Apache + tomcat + mysql (have to use JSP, no php)
2) 3 servers : Linux FC6 , 2GB ram , 2.8Ghz
3) Goal : to build a website to let people search the source code from
over 1 million files.

It is unable to use mysql to build the index from the source code
because people can search "int x=0" rather than english word, so all
the indexing server doesn't word. I guess every time the user submit a
search, i use grep command to search all the 1 million files. But it
is too slow, how can i improve it?

thanks
