There are lots of problems associated with the currently available search engines when using keywords to search for topics. One problem is that a search engine can find and return a vast number of results containing a large number of records that may have little or no relevance to the intended topic. This is because any topic can very easily be spread out and be linked to or from a vast number of records. Another issue is the problem whereby a document that is of high relevance may not contain the appropriate keywords that will precisely and clearly represent its relevance and classification. This is called polysemy (Jiawei and Chang, 2002). Taking these and other similar factors into consideration, data mining should be combined with the web search engines in order to improve the standards of the services provided by search engines. A technology called “Web-linkage and Web-dynamics analysis”, an index-based search engine (Jiawei and Chang, 2002) can be used to achieve this goal. The technology scans the websites on the Web for keywords and creates a large index database using the keywords and the synonyms to the keywords. When carrying out a search these keywords and the synonyms will then be used to find Websites that have them on their websites. In order words, the index-based search engine is searching for a larger set of records using keywords and synonyms while the individual search engines will search those records to obtain the most appropriate records that best match the search criteria. This will make it easy for power users to be able to find documents that are relevant to their intended topic by using a combination of keywords and synonyms
