After a six month hiatus, advanced search capability has returned. We apologize for the delays.
As I wrote back in February when the feature was introduced, many have observed that it is difficult to find older The Oil Drum content. Readers have had to rely on Google site search or the archives page. The advanced search feature is based on Apache Solr, which, unlike Google, enables you to sort and filter results. You can try it out by entering your search terms in the "Advanced search" box to the left, or by going here.
Feedback is welcome.
