Sierra de la Plata: The Sierra de la Plata ("Silver Mountains") was a mythical source of silver in the interior of South America.  The legend began in the early 16th century when castaways from the Juan Díaz de Solís expedition heard indigenous stories of a mountain of silver in an inland region ruled by the so-called White King.  The first European to lead an expedition in search of it was the castaway Aleixo Garcia, who crossed nearly the entire continent to reach the Andean altiplano.  On his way back to the coast, Garcia died in an ambush by indigenous tribespeople in Paraguay, but survivors brought precious metals back to corroborate their story.  The legend inspired other expeditions, all of which ended in failure.

Iterative deepening depth-first search: In computer science, iterative deepening search or more specifically iterative deepening depth-first search (IDS or IDDFS) is a state space/graph search strategy in which a depth-limited version of depth-first search is run repeatedly with increasing depth limits until the goal is found.  IDDFS is equivalent to breadth-first search, but uses much less memory; on each iteration, it visits the nodes in the search tree in the same order as depth-first search, but the cumulative order in which nodes are first visited is effectively breadth-first.

Google Blog Search: Google Blog Search was a specialized service of Google used to search blogs.  It was discontinued in May 2011.  The Blog Search was "the first major search engine to offer full-blown blog and feed search capabilities".  It was released in 2005.  The bots appeared to be faster than the standard Googlebot, because updates to blogs often become available within hours instead of weeks taken by Googlebot default.  The Blog Search searches were done identically to the Google Search by typing your search terms in the search field and seeing the most relevant results related to the topic.  The Blog Search looked at various services in the world of blogs like Blogger, Live Journal, and Weblog.  For some time it was possible to force Google to access and search the Blogsearch database by manually formatting the URL in your browser's address bar.  But in March 2016, Google also took away this access.
