I tried adding a Google Custom Search Engine to my Firefox search bar. The search URL Firefox created looked something like this -- containing
<my-custom-search-engine-ID> and the
But -- for some reason, this direct URL gives a
400 error: "400. That’s an error. Your client has issued a malformed or illegal request."
I can still use my Custom Search Engine, but only directly from the Google page. A couple of years ago this kind of direct linking/querying worked, though. What has Google changed since, and how can I find out the direct URL to my GCS queries?
Thanks for any help!
EDIT: A working solution seems to be creating a custom
search.html page (using the code obtained from your GCSE settings). But maybe a direct link to Google's default results page is still possible as well?
