How does Vertical search works

[coolrb]

Hi Group,
I got a project where I need to develop some sort vertical search engines to search books like simplyhired , indeed.com does for jobs. I could not able to find any useful information that can help me to twig or find underlying technology that work for vertical search engines. I know that they collect information from various search engines, but I am not sure how they work, like underlying technology, maybe some sort of documents on vertical search will be enough for me to get started. I would appreciate your suggestion/input.

Vertical search is in essence custom search. You can use Google Custom search to develop the engine. You would filter by keyword sets specific to the vertical and build out from there. Once you have the separated database it can be searched for that vertical...

Find out about Google Custom search and you are on your way.

Hi MrCool,

Even I have similiar question to yours...I'm sure by now,you would have known the devil behind Vertical Search engine..Can you help me to understand it..As I know Google Custom engine cann't provide Advanced Search with many widgets.

Appreciate feedback on KNow-How of this technology .

Well, after lots of research, I realized that vertical search is nothing but developing a search engine for niche market e.g. vertical search for Ad, Jobs, pets etc... I am currently using Nutch(http://lucene.apache.org/nutch/) for creating such kind of solution. Basically I have gathered a list of URLs, that needs to be searched for the said vertical search. Nutch uses these URLs to create search index and using Lucene API, I search such index. Though it is not that simply but this is the basic idea behind building any vertical search solution for any niche market. You might want to take a look www.ajaxtrend.com (http://www.ajaxtrend.com) search solution.
