Spivack explains:

Keyword search engines return haystacks, but what we really are looking for are the needles . The problem with keyword search such as Google’s approach is that only highly cited pages make it into the top results. You get a huge pile of results, but the page you want—the “needle” you are looking for—may not be highly cited by other pages and so it does not appear on the first page. This is because keyword search engines don’t understand your question, they just find pages that match the words in your question.

So how do we get beyond keyword search and Google’s PageRank? There are many approaches being tried: social search, tagging, guided search, natural-language search, statistical methods, open search, semantic search, and (way out there) artificial intelligence.

They all have their problems. Tags are too messy and inconsistent. Natural-language requires too much computing power, is difficult to scale, and doesn’t deal with structured data well. Semantic search is perhaps the most promising, but it essentially requires every single Webpage to be re-written.
