retrieving original html from database
I have an index of pages from the web, a bit over 1 million. The fetch took several weeks to complete, since it was mainly over a small set of domains. Once we had a completed fetch, and index we began trying to work with the retrieved text, and found that the cached text is just that, flat text. Is the original HTML cached anywhere that it can be accessed after the intial fetch? It would be a shame to have to recrawl all those pages. We are using Nutch .8 Thanks for any help. -Charlie

We are using Nutch .8 If you have fetcher.store.content set to true then Nutch has stored a copy of all the pages in /content. You can extract individual contents with the command "./nutch readseg -get -noparse -nofetch -nogenerate -noparsetext -noparsedata". Thanks for any help. -Charlie -- Doğacan Güney

Re: retrieving original html from database
You can try this command: bin/nutch readseg (-dump ... | -get ...) . If you need an API instead of the command line, you may have to hack the segment/SegmentReader.java? I'm also wondering this. BTW, make sure you set the 'http.content.limit' property to -1 to avoid content truncation. songjue 2007-04-27 发件人： Charlie Williams 发送时间： 2007-04-25 22:43:12 收件人： nutch-dev@lucene.apache.org 抄送： 主题： retrieving original html from database I have an index of pages from the web, a bit over 1 million.

Re: retrieving original html from database
If you need an api for getting the content, can't you just look into the cachedContent.jsp of the demo search application? That shows how to retrieve the original text/html that is stored within the segments. Perhaps I am missing something.
