Recap

As described earlier, I've placed many a Google web search block into Drupal sites, using Google AdSense for Search.

All to a single end: the blocks don't work. (Hey, consistency counts for something, right?)

I replaced Drupal's built-in search with Google search on several sites. From my Google AdSense account, I created the AdSense for Search code, and plugged into a Drupal block.

For a while, it seemed to work fine. The user selects whether to search on the web or on the site, inputs the search terms, and hits the button. Appropriate results show up on a "search results" page (which is a regular Drupal Page containing HTML code specified by Google, to catch and display the search results).

That's our Drupal: you'll be racing along, everything finally shiny and tuned and humming, and suddenly she'll throw a rod or blow a gasket or nip a node title or something.

Or maybe that's tech in general, not just Drupal. But anyway.
