Search Machine for Ubuntu machine

[Ted Hilts - Thunderbird Acct.]

 I have Ubuntu 7.10 and would like to get an open source search engine 
which I can use on this machine.  I would like to tell it what hard 
drive and/or directory to search and tell it to search for a file and/or 
contents of a file.  It would also be nice if it was written in perl or 
java or java script or python or some other script or language but not 
compiled.  Even a bash shell with bash commands. Also, I would like it 
to be a server so clients from other machines (like XP) could access the 
search  domain.  I suppose I could use a browser as client which gives 
Apache a CGI script with the results back to the browser but I  am 
hoping not to develop  this application but rather (at least initially) 
to pick up a search application ready to go.

Thanks -- Ted.
