Thanks again One more question ;)

Is this tool (google parser) going to be available for download? I see download section but no source code yet :( I think it would be great php/curl maybe regex learning lesson. I would like to develop something similar. It should run multiple queries in batch mode. It doesn't have to be fast but should be stable. In your experience, if the queries run with like 2,3 seconds timeout should I face the captcha? I would like to develop similar way for user to fill captcha input and continue with queries. The problem is that processing script should run in the background - not the same script that generates user interface. Regards Thanks for the quick response!

I use Curl library for the HTTP requests, with it I can use the same cookie for several GETs or POSTs. To represent a session I just use the same cookie, when I want to start a new session I delete the old cookie and done. Cheers Milan, you are right.

Actually what do you have to save in the cookies in order to continue search. I guess you use curl library? Regards, Milan How do you ensure that saved cookie is for the same session?

A year ago when I used this API, you can only get the first 8 results for a specific search and you can't paginate over the rest of the results. So if you don't need the rest of the search results this API could be good for you. I just read that now the Google AJAX search API gives you the first 32 results and pagination only over them. Still the same limits but with a few more results. Basically, number of results limitations and no pagination over the rest of the results.

I didn't use the previous SOAP API because when I want to use it Google are no longer giving new API keys. Thanks for the links, I will check them. BTW: I modify a little your second link to prevent problems with my advertisers... Kamil, I tried the Google AJAX search API, it has too many limitations.

For another things Google has many datacenters but they are synchronized, they can delay more or less in synchronizing... in the case of the blocked IPs, I think that Google has all of them centralized, they can be distributed in several servers or in only one, but I think that it isn't a very large amount of data that needs to be in many datacenters. This is just my opinion, I don't know for sure, I never get in the Google internal network... he...
