[xwiki-devs] Fews doubts on GSOC project "Distributed XWiki Search Engine"

I am planing to work on the project "Distributed search for XWiki". I have few doubts, which might sound silly, yet I would like to clear them. Please help me. """Support multiple installations of XWiki being indexed on one or multiple XWiki Servers and share the index. It should be possible to share easily the index so that multiple XWiki installations can be shared in one UI.""" ---> I am assuming that one of the several servers, is the main server and has information about other servers like the ip address. -- am I correct ? ---> Can each server maintain it's own index(instead of distributed indexing), but while searching, indexes on multiple servers are used. ---> please provide me some more info regarding this. """Also the search UI should be possible to customize depending on Document types.""" ---> Restricting search to specified document type. If any one has other relevant information, please provide it. -- Sai Krishna.
