Search engines for Intranets

As Intranets become more common place, the need for implementing the ability to search for content has become more important. Without a search engine, much of the content that makes up an Intranet is lost. With so much importance placed on this tool, it is imperative that thoughtful planning precede the implementation How does one choose a search engine? What criteria are used? What steps should be included in the project plan for putting a search engine in place? Additionally, many commercial web servers now include a search engine as part of the server package. It would seem that a built-in component would be simpler to install, easier to maintain, and less expensive. How do those search engines stack up against the commercial third-party products? Are they easier to work with? Do they meet user needs? A comparison of the search engines delivered with Novell's intraNetWare, Microsoft's NT Server and Netscape's SuiteSpot Server shows the strengths and weaknesses of each product.
