Linden Lab announced the arrival of a new (and, hopefully, improved) search engine for the Second Life Marketplace.
The new Search still supports Boolean logical operators (NOT, OR, and AND, typed in all capital letters.) LL did not specifically say so, but this writer hopes that the new search is less sensitive to the case of search terms!
The new Search, according to LL, is "smart", in that it will learn from your searches and get better with continued use.

(And, for any of you who are new readers, this post, like all "FLASH!" posts, is a very short announcement of an item of late-breaking news!)
