  Search Engine has become a major tool for searching any information from the
World Wide Web (WWW). While searching the huge digital library available in the
WWW, every effort is made to retrieve the most relevant results. But in WWW
majority of the Web pages are in HTML format and there are no such tags which
tells the crawler to find any specific domain. To find more relevant result we
use Ontology for that particular domain. If we are working with multiple
domains then we use multiple ontologies. Now in order to design a domain
specific search engine for multiple domains, crawler must crawl through the
domain specific Web pages in the WWW according to the predefined ontologies.
