Subject Re: Trouble indexing a Twitter search in RSS format
Date Tue, 16 Aug 2011 09:49:56 GMT
Hi Kate,

Another point you should be aware of - this site has a robots
exclusion for crawlers, so unless you override that you will not be
able to fetch either feeds or content.  There are two ways to do the
override - you can set it to just allow the feed itself, or you can
set it to allow both feed and content.  If you select the former, then
any secondary (document) fetches will be disallowed.

Should you crawl repeatedly when the site owner says "no robots", you
can also wind up being blocked by the site owner.  In that case your
crawls will all cease to work suddenly and without warning.
