asks: "With more and more sites going to a database driven design, and most search engines not indexing anything that contains a query string in it, we're missing alot of content. I've also heard that some search engines won't index certain extensions like php3 or phtml. Is anything being done about this? How can you use dynamic, database driven content and still get it indexed into the major serach engines?"
Is keyword searching obsolete? Do you think its time to index sites by the type of content they carry rather than the content itself? Will larger indexing databases (or a series of smaller, decentralized ones) help?
