Search API enhancements?

As we're getting more of the enhanced Lucene search server's
capabilities exposed to the web UI, it might be good if we can make sure
they're exposed to the API as well.

I received a request recently specifically about the "did you mean"
feature for spelling corrections of search terms. Internally this is
exposed as the hasSuggestion(), getSuggestionQuery(), and
getSuggestionSnippet() methods on the search result set object for
search engine backends that support it.

Being able to return this via the API could be rather handy...

Do we have a standard way to return a query-specific bit of metadata
with the alternate search term suggestion as well as the list of
individual results?

IMHO we can just add another element next to <search>, like <searchSuggestions>

http://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=meaning
returns

<api>
...
  <query>
    <search>
      <p ns="0" title="Meaning" />
      <p ns="0" title="Semantics" />
...
    </search>
    <searchSuggestions>
      <s>suggestion1</s>
      <s>suggestion2</s>
    </searchSuggestions>
...

I'll try to poke at this some time this week, although I can't make any
promises (I've been busy lately, there's virtually no time left for me
to do MW stuff on Mon-Thu).

No. I'll invent one :) Yuri's suggestion looks good, although I'm wary
of CamelCase in XML tags (but that's just a minor detail). I'll probably
make this optional through srprop=suggestions.
