how to store very large XML Documents

[null_pointer]

Hi all ,
I need to accept large text documents from the users and store them on the server, which can then be searched(free text search).
whats is the best way to store such docs.
i was thinking of XML but since the document will keep increasing (its like a book where you keep adding new chapters)
i dont know how effective will a free text search will be


Can some one please let me know what the best way to handle this(i am using jboss3.0)

Thanks

IBM tuple net server has a really good XML storage.
there are also lots of XML database projects.
