In Google, it is possible to do site-specific searches like this: site:www.thedaobums.com (search term)
However, Google's crawlers do not reach the PPD section, where a lot of interesting content can be found. This site's search engine did (or still does but just for the past two months). I'm wondering if the mods could experiment with re-setting the search scope further back in time to see if it affects connectivity and speed? If it is negatively impacted, by all means go back to two months. Just a thought. (You may have already tried this, apologies if so)
I'd also like to thank the mods/concierges and IT people for all you do!
