How can one re-point searches at different segments ?

[Nathan Hale <pe...@hotmail.com>]

Hello,
I have 3 independent .db and segment sets that have been crawled 
individually and are now placed in 3 different folders side by side.
I have 3 different websites that use nutch search, each needs to be pointed 
at a different .db and segment.
How can I do this while maintaining one copy of Nutch on same Tomcat server, 
without having to run 3 separate instances of Tomcat?
Seems to me this would require re-compiling an element in search.jsp to read 
3 scoping variables passed to it via query string, but I can't figure out 
which component in search.jsp controls where nutch is pointing its search.
I suspect it could be the NutchBean.get(application) call,, does anyone have 
any experience or insight with this?
