_panels_page_get_title returns an empty title when you use a panels display. Use use empty() instead of isset().

Rather than hook_form_alter, you should look at hook_search_preprocess.

The block delta is a string, and not a number, so this query needs to use %s instead of %d.
The column definition from system.install is:
   delta varchar(32) NOT NULL default '0',

When the link says "bookmark this" after page refresh (not after any ajax), if you click on the link, the ajax properly updates the database, but the jquery doesn't properly update the text such that the link still says "bookmark this". If you refresh the page at this point, everything is OK. But if you don't refresh the page, this link says the wrong thing.

I have a need for hook_delicious to sometimes support exact matches and other times to support LIKE matches. To support this, the array returned by hook_delicious can now defined an array element named 'like' => TRUE, which tells delicious to use SQL LIKE. I've implemented this in the 5.x branch, but this needs to be ported forward to the 6.x branch.

Thanks for the module!!! What was the reasoning behind disallowing hierarchical taxonomies?

The {search_dataset} has a unique key named "sid_type". Because of the query in search_wipe, which is called on every single sid that gets indexed, this unique key should be an index.

The search engine is indexing javascript inside of <SCRIPT> tags. See #257076.
The solution is to put script javascript inside an HTML comment. This is what we had to do in the 1990's when some browsers didn't support script. And I think it's still good practice.
