This PrefixQuery will be very useful for hierarchical document systems where
you want to restrict search and updating operations to a specific sub
tree (see the draft of the new FAQ at
http://lucene.ontero.com/faq/faqmanager.cgi?file=chapter.search&toc=faq#q36)
.
You simply restrict your operation to documents whose path field contain
some prefix.
Will it be possible to use this prefix feature also to delete a subtree ?
Currently
the delete() method accepts only an index or a Term but not a Query.
We use hierarchical delete in our system when a sub tree of the document
store
is modified (delete, root folder renamed, etc).
