MSN Search
is a crawler-based engine put together by Microsoft and incorporating proprietary Microsoft technology in its search services. There are three factors (probably many more, but these are the main ones) that MSN uses to put together its search index:
- MSN Search's spider, MSNBot, crawls the Web one link at a time in order to find pages to add to MSN's index
- The index generator technology sorts pages into ranking, subjects, directories, etc. Think of a post office here, with every letter going into a particular box according to zip, address, mail class, etc.
- "Query Server" - from the How MSN Search Works page: "The final piece of the puzzle is the query server that matches your search terms with the index's ranked sites. The query server analyses your search terms and compares them with each page's rank to determine how relevant each page is to your search terms.
