Hacker News | Follow on: Use DBMS or fs?

  • Another reason to not use a DBMS for a search engine is that typical implementations of transaction-oriented SQL databases are a terrible fit for the performance requirements of a search engine. For example, search engines don't need concurrent writes or ACID transactions, or SQL-like query language; search engines want to optimize for large-scale updates, not small, random writes; typical DBMS index structures (btree) don't work well for search engine indices.

    Eric Brewer has an interesting paper that lays out an architecture for a search engine that is consistent with DBMS design principles, but differs significantly in the implementation details:

Search Y Combinator - Blog

  • Some have speculated that we've moved on. And while that's true to some extent, we are still actively maintaining this website as a service to the YC community. Call it a personality flaw, or whatever you want, but there's just something about letting a website die that doesn't sit well with me.

Leapfish Launches Another Meta Search Engine No One Will Ever Use

  • The answer: people don’t want to get as many search results as possible and they don’t care about how large the unindexed part of the internet is, let alone what they might find on this so-called “invisible deep web.” All they want is a quick, convenient way of obtaining decent information from a source they know and trust. Or do you honestly visit Search.com, Dogpile, Zuula, Fazzle, Clusty or Mamma.com to get what you need? (I can go on with this list forever, but ask Mark Cuban about how much that last one is worth).

Yahoo! BOSS in the right direction, but only BOSS Custom goes far enough for radical search innovation

    • Three levels, but only BOSS Custom has real potential for a highly differentiated service offering.


      There are three levels to the BOSS program, according to SearchEngineWatch:


      • self-service API
      • BOSS University for academics
      • BOSS Custom, designed for companies with their own ranking and/or presentation methodologies. Or alternative, companies with proprietary data that can help as an additional signal that factors into relevancy.

      I’ll go over all the aspects of the BOSS program below, and then come back to BOSS Custom as evidence that Yahoo! just might Use The Force. But the basic features looks like a free version of Google Custom Search Engine.

He wanted an iPhone search experience that matched the desktop experience and took full advantage of Mobile Safari’s excellent featureset. And he wanted it in a month.

UCLA study finds that searching the Internet increases brain function / UCLA Newsroom

  • UCLA scientists have found that for computer-savvy middle-aged and older adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function.
  • Internet searches revealed a major difference between the two groups. While all participants demonstrated the same brain activity that was seen during the book-reading task, the Web-savvy group also registered activity in the frontal, temporal and cingulate areas of the brain, which control decision-making and complex reasoning.
