Search robots getting smarter

Enough Keyword Searches. Just Answer My Question.

From the article:

There are efforts in question answering going on at lots of universities and companies. Statistical methods that extract passages from source text are very popular these days. In this regard, Google can be considered to be a sort of QA system.

Google has a search component that looks for pairs of associated words. This lets it correct your query when you search for "marshall brane" and not when you search for "physics brane".

Unfortunately, this feature prevents you from finding pickled asparagus using the search "briny spears".
