These slides are from a talk that Tyler Tate presented at the Enterprise Search London meetup on February 4, 2010.Careful observation seems to reveal three different approaches to search suggestions: completion, suggestion, and instant results. These approaches range in cognitive burden on the one hand, and utility on the other.Completion is easy to understand and almost always results in a net benefit for the user. Suggestion, because it throws new ideas in the mix, is slightly more complex, but that is usually outweighed by its helpfulness. And finally, instant results work well for simple, highly structured data, but at times runs the risk of overwhelming the user.

Completion: Bene ts almost always outweigh costsSuggestion: Usefulness varies by accuracy of suggestionsInstant Results: Works best with highly structured data that need only return a few results 11. Experimental Ideas 12. Questions for Discussion Do the three categories make sense to you? Do the search suggestion implementations youve worked on fit into one of these categories? Ideas on when to / when not to use suggestions? Do you have other experimental ideas? 13. @tylertate
