Same thing for me.. needs a couple of refreshes on the same query before I can 
get the actual response...

caching problem?

Just to reiterate what I said on the link omr posted, according to 
conversations with the dev team, this behavior is a design feature of the Feeds 
API. Essentially, if the feed is slow or fails to load, or the crawler takes 
too long to parse and cache it, the Feeds API will essentially time out and 
return the response indicated above. This way, the client doesn't keep sitting 
there waiting for a request that may or may not ever finish loading.

The good news is that, once the feed is cached, you shouldn't receive the 404 
response very often at all.

Sorry for the delay, but I think we've gotten this fixed.  Please report back 
here if you're still seeing the problem.

• Changed state: Fixed

[GoogleCodeExporter]

I think this bug is still there. I followed exactly the same instruction in the 
Feeds API page and randomly get the 404 response. Please open this again.

I have the same problem with Google Books API. 404 response returned randomly, 
same query may work few seconds later.

URL example:

https://ajax.googleapis.com/ajax/services/search/books?v=1.0&q=ajax&key=MY_KEY&u
serip=MY_API

Please let me know if I should open new issue for Google Books API. Thanks.

I am getting the same in patents all of the sudden

http://ajax.googleapis.com/ajax/services/search/patent?v=1.0&q=dogs

[GoogleCodeExporter]

books, patents, and images are all failing the same way.
It does not seem to be a cache issue, since my search

http://ajax.googleapis.com/ajax/services/search/books?v=1.0&q=cats

succeeded once, two days ago, then failed the next hour.
It would be surprising if it were a timeout issue, since it fails in less than 
a second.

Hello, thanks for pointing out the issues around the Books and Patent Search 
APIs.  As noted, this is unrelated to the former Feed API issue, and wasn't 
timeout related.  Sorry for the delay in fixing it, but it should be good now.  
Please let us know if you continue to have issues (be sure to include the query 
that results in the problem).

Thanks!
Adam
