Well, they could at least address the case where a typo returns no results, but a correction would return results. I think this is a common enough scenario to be useful. They could also return the union of misspelled words and likely corrections, or offer the latter as “did you mean” suggestions.

Personalized dictionaries would be awesome, but perhaps that is more load than their servers can bear. But I’d settle for suggestions based on global statistics. There’s only upside here.

I was wondering about *exactly* the same thing today!

Offering the web-version of the “did you mean” seems trivial. However, it does not sound too useful to suggest the “correct” spelling if you do not have any emails that will match the correct suggestions. It may actually cause more frustration due to “false positives” (suggestion that return 0 results)

I assume that they would like to have a customized version of the feature for each user, personalized for each user’s archive. For that, they will need to keep some “local” statistics about each user’s character and word n-grams to get this feature to be functioning as on the web. However, I assume that most users will not have email archives big enough to generate reliable n-gram statistics.

So while such a feature would be useful for the occasional typo, it may not be good for suggesting the alternative spellings that will lead you to actually find emails in your own archive.

Or at least this is the explanation that I came up with…

I’m sorry I wasn’t clear. I don’t mean spelling correction of the email, but rather of queries in the Gmail search engine. If I misspell a term in the search box, I get no results. I’ll try to clarify that in the post.

You can spell check in Gmail, it’s in the top right corner of the message compose box. Not the same as spell-checking while you type, but also doesn’t annoy you with red underlines..
