Search is definitely harder to use for poorer results than it was way back. You have to start by ignoring the Search box; click on the Advanced Search link below it, which opens up a page with tabs (all this is as clunky as Windows3) and what you're looking for is Single Content Type. Selecting that tab will display a teensy window, way too small for all the 'single content headings' TERB has determined we want, but in amongst them as it scrolls too fast, you'll find (Incall), (Outcall) etc.
Still no way to retrieve those posts by guys who abbreviate to less than four letters though: like CB insteadof maybe CnBl, or DM for DreamMkrs. One just has to assume such posts contained no useful info.
Hope it helps
