Here, I want to return either a UWYT match or a SWYT match (using the current
view_->GetText()), depending on |is_instant_temporary_text_a_search_query_|.
Currently, the portion of search_provider.cc that adds the SWYT match is tightly
intertwined with the rest of the code. HistoryURLProvider::SuggestExactInput()
is more easy to re-use (given it's already re-used for the Ctrl-Enter case).

What do you recommend I do here?
1. Pull out the necessary parts to enable reuse?
2. Something else (perhaps an entirely different approach altogether)?

[Peter Kasting, 2013/04/08 20:13:50]

So to be clear, the reason that running through the Classify() case won't work
here is because you have text that looks like one thing but should be treated
like the other (e.g. a search for "facebook.com")?

If so, I would say factoring the SearchProvider enough to allow for creating a
SWYT match directly is fine.

[sreeram, 2013/04/08 20:20:48]

Exactly.
Thanks. I'll do that and ping this thread when the patch is ready.

K, make sure to make that clear in the comments here.
