VERTIC (Vertical Search Engine)
• A vertical search engine, as distinct from a general Web search engine, focuses on a specific segment of online content. The vertical content area may be based on topicality, media type, or genre of content.
• Vertical search engines are also known by the term ‘Vortals’.
• I have chosen the name ‘Vertic’ for my vertical search engine.
EXISTING SYSTEM
• There are many search engines in the market which offers wide range of searching services like Google,Yahoo,Bing and many more. These search engines are known as ‘Generic search engines’, as they have a wider scope of searching and they search the whole world wide web for a given keyword. This approach often results in undesired results.
Disadvantages of Existing System
• Regardless of the growing sophistication, many well thought-out search phrases produce list after list of irrelevant web pages. The typical search still requires sifting through dirt to find the gems.
• Even the most powerful search engines on the web gives ‘irrelevant search results’.
• Using search engines does involve a learning curve. Many beginning Internet users, because of these disadvantages, become discouraged and frustrated.
Proposed System
• ‘VERTIC’ is the name of the proposed vertical search engine which is a web application designed for performing vertical search.
• Vertical Search Engines (Vortals) does a more ‘focused search’ in only predefined domains (specific segment of online content ) provided to it during the development phase.
• These Search engines use a ‘focused crawler’, instead of ‘web-crawler’ used in generic search engines
• The Scope of Search of these search engines is very limited and do not search whole world wide web. Hence they produce results with more accuracy and efficiency.
Advantages of Proposed System
Vertical search offers several potential benefits over general search engines:
• Greater precision due to limited scope.
• Leverage domain knowledge including taxonomies and ontologies.
• Support specific unique user tasks.
• Produces accurate results by filtering undesired results.
Scope
• The scope of my mini-project is to develop a vertical search engine, which gives the most accurate results to its users by filtering the undesired results.
• Vertical searches only from the predefined domains provided to it and cannot search anything which is not included in these domains.
• Vertic is different from other vertical search engines in the market as it includes an additional feature called ‘custom search’, which helps the user to obtain more detailed search results.

High Level Design
1.User Module:
• The End User is provided with a Home page where he is given a Search field to enter the “query” or “keyword” that he want to look up for in the internet. The Search Field is accompanied with a check-box and two buttons.The two buttons namely “Search” and “Advance Search”.
2.Normal Search:
• After entering the query into the search field, if the user hits the Search button, then Vertic (Search engine) will return relevant results on that query only from the domain he/she picked up in the Domain check-box.
3.Advanced Search:
• When the user chooses to perform advance search in the required domain, he can use this option. After selecting the domain, when user hits the Advanced Search button, he/she is redirected to a page which consists of a form asking more details and specification of what user wants to search for in the internet.
4.Search Engine:
• Vertic is a search engine developed to search the queries given by the user in the internet. In this technique, the irrelevant results are totally eliminated and the user can perform a more detailed search in the internet and filter results by him to an other level.
