    I don't understand the sentence: "The new crawler creates an in-memory reverse index to scale for a comprehensive search of its 28 million users."

    Does this actually mean anything? It's the "reverse index to scale" part.

    "We wrote a crawler for the site, created an in-memory reverse index using both hashes and ternary tries and created a ranking system that scaled to return unique results for over 28 million user profiles."

    There's a few ideas crammed into the one sentence:

    -data structures in-memory to serve the barrage of hits and cover their vast size
    -unique results for each of 28 million members over the same space of users
    -reverse index related to the representation of the search mapping in terms of the social graph?

    It's amazing how people are more concerned about others rather than themselves. OMG my friend Pedro in Mexico just got a new hat! I gotta check out his pics.

    :)

    Thanks, Minger. I can understand the sentence in full, but I suggest the original, shortened version is just jargon collapsed into something that didn't make sense. I'm glad it got edited out. :)

    Cool.
