Falsehoods Programmers Believe About Search
I think this article is setting up a pretty high bar for search. For small datasets, you can very well just add an automatically generated "description" column in your database, and then do a SQL LIKE query: it's a simple substring matching.<p>It's by no means smart, doesn't handle misspellings or anything, but it works reasonably fast and predictably. This is basically how almost every desktop app with a search bar works. This is how word processors and editors work when users search within the document.
