> We have huge index of stored documents. It is high cost procedure to fetch
> page, merge indexes any time we update some information about page. The
> information can be changed 1-3 times per day. At this moment we have to store
> changed info in database, but in this case we have lots of problems with
> sorting, search restricions and so on. Lucene itself allows delete single
> document and add new one into existing index. But there is a problem with
> hadoop... As I understand hadoop filesystem has no possibility to write in
> random positions. But it will be great feature if nutch will be able to
> update created index.
