Easy Web Search is engine to use inside a web site. Simple Crawling System is available to submit URLs and Links and XML Site Maps. URLs From submitted Sites or Site Maps will be automatically added to search database when admin run crawling. Once crawling is done the links with their contents (Title, Description, Keywords and Plain text from web link) will be available to search. If the total web site is linked to it’s home page, you need jut give home page url or xml sitemap to the system and run crawling once. You do not need to much work to implement a search system inside your web site. Any link associated in the database will automatically updated when users view the pages. So you need to run crawling at admin area only for adding new links from sites/site maps. And if you think some links are not to update when users view page, you can just disable update from admin area for that link.
