Daniel Lew's post search engine result display made me think about the vertical search engines. Vertical search engines are entirely different from the general search engine's like Google,Yahoo and Bing. Vertical search engines know their visitor and they are made based upon the visitor's interest. You can easly find a lot of travel based vertical search engines like Kayak. There are search engine which go beyond the general search engine feature to provide results based upon word relation in context to search query. Truevert is one such search engine which provides true vertical results beyond general search engine niche intention based result. Another interesting search engine I came across was Bossy which provides single answer to visitor queries.

An example is

Question:: When did germany invade poland ? Answer:: Month: Sept Year: 1939

The latest computational knowledge engine Wolfram Alpha was intended to provide visitors with systematic knowledge on their queries.

Where is the search heading towards?. The search engine future might go beyond general search engines as new signals of relavance becomes important. Certain factors like user behaviour, speed of providing search results etc will play a much more dominant role in the coming years and this will make general search engines to start taking measures to understand about the user query signals to stay on top of the search industry.
