Well the way that nutch works is that you would inject your list of domains into the DB, and that would be the starting point. Since nutch uses a crawler it would grab those pages, and determine if there are any links on those pages, and then add them to the DB. So the next time that you generated your urls to fetch, it would take your original list, plus the ones that it found to generate the new segment.

If you wanted to limit it to only pages contained on your 10000 domains, you could use the regex-urlfilter.txt file in the conf directory to limit it to your list. But you would have to create a regular expression for each one.

I am not familiar with the merge script on the wiki, but have merged segments before and it did work. But that was on Linux, don't think that should make a difference though.

Hi,

Thanks for the reply. I have list? of those domains only. I am not sure how many pages they have. Is a DSL? connection sufficient to run nutch in my case. Did you run nutch for all of your pages at once or separately for a given subset of them. Btw, yesterday I tried to use merge shell script that we have on wiki. It gave a lot of errors. I run it on cygwin though.

Thanks.
A.

I think that in order to answer that questions, it is necessary to know how many total pages are being indexed.?
?

I currently have ~3.5 million pages indexed, and the segment directories are around 45GB, The response time is relatively fast.?

In the test site it is running on a dual processor Dell 1850 with 3GB of RAM.?
