1. what is the vertical search actually? it means we can create different search engine for different topics in different industry based on the business requirement?

    so it means we can find a template or a model for different purposes, so WHere is the model or template? can we create by ourself?

  2. I think vertical search is a little more than aggregating search and putting a business front end on it. Whonu.com is a Semantic Web search engine, why not watch the video on their main page (26 minutes long)? “For example, enter a US ZIP code and whonu presents a set of links to geocode tools including maps, weather maps, and even public events in Google Calendar.” Sort of mashup/search/personalisation. It is hard for me to grasp exactly, but I’m working on it. 🙂

  3. you are right

    1, web spider get all web pages as words in hashtable stored in cache
    2, then use keywords to search relative words in cache
    3, output the search result as html with links
    4, discard cache when leaving the session

    that is all

    here vertical search limited the web pages access . not like google search all web. urls is defined by vertical search codes. This is why you can see the topic search not whole search.

    C# web 2.0 can be used to create spider to get all words from web site and store in hashtable for further search

    I have developed a spider page that can get all words from a web site. But I am surprised The program can not search your blogger contents. it is interesting. i am working on it

  4. whonu.com actually uses Google Search Engine plus their own search logic to narrow the search from the web. this is a quick way to create vertical search by using the known search engine. but if you want to develop your own search engine for special client. you should create spider to crawl robot.txt contents to get index url and meta data info from the web site.

  5. Hmm I don’t think that’s right. They use over 300 search engines (click the arrow on the right hand side NEXT to Google). Google represents 32 of those search options.

    This is aggregated search, shuffled and mashed up and redelivered. Check the video – you can put in “tallest building” then it delivers not only Google/Yahoo search but also brainbooster and Answers.com. Intelligent search…

  6. you are right. what whohu do is to pass the search string into different search engines.

    but after you search the default search engine, your search string is limited being used in this search engine for intelligent search. it means spider uses the URL index database in this search engine to crawl the search keywords in this database and give you the so-called intelligent search options under your search string input panel.

    So what whonu.com do is
    1, collect different search engines
    2, set one search egnine as default
    3, input search string
    4, this search string is trapped into the default engine
    5, default engine search its URL index database
    6, return relative search keywords to narrow your search words down
    7, then you still need to click default engine button such as “google” to get links from the web.

    Actually there is nothig new. but the search way is improved.

    My idea is

    if we can find a spider to crawl all search engines URL Index Database(it means we can access all search engine database in one click), we can organize all search keywords in smart way as whonu.com did. Then we can eliminate the 300 search engines options.

    However, it seems we canot achieve this goal because each search engine will not allow third party spider to crawl their index database without permissions. Therefore, we have to use each search egnine for search. what we can do is do what whonu.com did. make search smarter.

    but from this topic, I found out the way to spider all words in a web site. this search makes me to search any words in a web site to get their links possibly. This is more useful than whonu.com did.

    we can build our own spider for different web site to search their own web contents. because if a company’s web site become a huge mixxed bytes space, even company web developer can not find the suitable contents in this huge site in second, however, the spider could allow you to make your search in seconds.

  7. Fantastic items from you, man. I’ve consider your stuff prior to and you’re just extremely fantastic.

    I actually like what you’ve got here, really like what you are saying and the best way wherein you are saying it.
    You’re making it entertaining and you continue to take care of to stay
    it sensible. I can not wait to learn far more from you.
    That is actually a wonderful web site.
