data-entry

Given a very large database of product names, how would you detect possible typos in user searches and suggest possible corrections (Kinda like the way Google presents them)? E.g. User enters "fork handels" and presses 'search'. They get back "No results. Did you mean 'fork handles'?" There are several approaches for this problem: Keeping a table of most popular misspellings in your database. If you need some common misspellings: here ) Using an algorithm based on the edit distance : In information theory and computer science, the edit distance between two strings of characters is the number
