Embedded search in arbitrary web sites sucks because it's a hard problem. The naive solution is to put all text in a database table keyed by "page" and do a sql "like" query. Don't ever do this. Some db's have full text search nowadays. I've implemented "embedded" search a few times in the past and I used Lucene, which actually works pretty well.
