[tomap]

geocoder api supports between 1 and 10 search results. Default value is 5.
Now, it's possible to set the limit

Hey, you published a new version recently, could you look at the PR?

Thanks for flagging this, @tomap. As far as I can tell this looks like a pretty straightforward change, but before we approve/merge would you mind doing the following two things:

• add a unit test in https://github.com/mapbox/mapbox.js/blob/publisher-production/test/spec/geocoder.js for this new query parameter
• update the CHANGELOG.md to reflect this addition

4 years later, would you mind doing it? I did half the job. I would be very glad if you did the rest of the job :)
