We want to get some search-logs from wikitech to find out what people are frequently searching for, in order to improve the documentation.
I asked if this was currently available in -discovery IRC and Erik replied [edit for clarity]: "there is lots of it. Most likely you would be looking in wmf_raw.cirrussearchrequestset -- there probably will be [followup questions], the data is pretty raw and not the most obvious to understand. Feel free to come back with more questions :)"
Filing before I forget.
