Microsoft seems to be ahead of its rival Google when it comes to recognizing new gTLDs in their respective search engines.
Doing an advanced search for sites within specific new gTLDs on Bing is returning results today. The same cannot be said for Google, however.
Here’s an example of a search results page limited to Uniregistry’s .sexy:
The same type of search seems to work for .tattoo (Uniregistry) and .ruhr (Regiodot) but not for .uno or for any of Donuts’ many Latin-script gTLDs (which all currently redirect to donuts.co).
Sometimes the searches work with a dot, sometimes they don’t.
New gTLD support appears to be a work in progress at Microsoft, in other words, but the company does seem to be further along than Google, which so far doesn’t return any results for the same queries.
