I am still trying to subscribe over a slow internet connection....

So far I have noticed that the terms and conditions are not suitable for a search engine, they are the standard commercial terms and conditions and do not apply to the application being mostly linked to the purchase of goods and services rather than the usual legal issues of a web service.

I got to the search term page ok, but when I tried to pass beyond it, after setting my search terms, it gave me a "500 Internal Server Error" and mentioned that the "error page" it had selected had returned a 404 "Page not found" error, suggesting that there are some files missing in the error tree, or an error in the link to the error file. Sorry, I couldn't get beyond the error yet, so I can't further comment.

Thank you so much.

Having had the digest version dumped to my e-mail for a while now, I can comment on the search accuracy, I note that none of the articles listed in the news actually involve my search terms. Further the search engine is selective and only lists about 4 of the six searches I asked for, and always the same 4, in other words this is not an effective search engine. Lately some of the articles have been blog posts, not actually articles from the so called magazines that are purported to be being searched. In short the quality factor is low and this Invitrogen search engine can be classified as a form of spam, masquerading as a search engine. I note that the request has been removed, this is probably wise.
