What is an Answer Widget?
You'll notice that there is an answer widget which appears on the right side (desktop) or top (mobile) of the results list. This is triggered via your search query or words in your search query. For example, AAPL appearing in a query will trigger an answer widget containing a stock quote for Apple Computer since AAPL was in your query. Or a search for "null pointer" will trigger a wikipedia answer.
Is only one displayed at a time?
Ideally, we prefer to only display one answer widget to avoid too much clutter. We show the one with the most relevancy (trade secret), however, it is possible to have 2x very relevant answers and have both shown. It all depends on the query.
How many widgets are there?
We're adding more every day and always tinkering with relevance. Here is short list of active or very close to being active answer widgets: Wikipedia, Stock Quotes, Dictionary, Unit Conversion, Weather Forecast, Skiing Resort Info and Trailmaps, Automative Specs, and more pending.
