If I (or you) type in, for example "20W-50" in 'subject and body' for All Forums over the past 11 months, the result is: "There are no results for your query. Please try a broader range of search criteria" There is, however a 15 page post "Why The Dislike For 20W-50?" spanning 12/07/14 to 12/27/14. Why isn't the search function finding this? I'm particularly interested in UOA of 20W-50, but find nothing. I've also tried 20W/50 with the same results.
