Hey Developers,
About a month ago, we announced important Search API changes, including the support for URL, media and hashtag entities. Today, we're happy to let you know we'll be supporting user_mentions starting from the 1st of December, achieving parity with other API Resources supporting Tweet Entities.
There will be no specific action required on your side, apart from using the include_entities parameter to include entities in Search Results.
As always, please let us know if you have questions around this change or Tweet Entities.

Cool. I already have a test page for Tweet Entities and will be making the necessary modifications to test this addition.
Any plans to include the sender's full user object in the payload, instead of just their id and proflile_image_url?

Cant see the mention and requests made to me by my followers and persons who I follow in my android twitter app and in win7 laptop..please solve this developers
It's December 1st -- and in just a few minutes, requests to the Search API with include_entities=true will begin including user mentions entities, along with the entities for URLs & hashtags already present (assuming the tweet should have mentions entities).
This brings parity to the entity portion of the Search API in relation to the entities provided by the standard REST API.
More Search API improvements are on the way, stay tuned!
Already had the code for this in it for ages. Very glad user_mentions are about to be supported by the search api as well :)
Also, wanted to add that we'll begin serving the "in_reply_to_status_id" field on @replies today in the Search API. This has been a long time coming.
Great news, glad to see so much progress on this!
Do you have any plans to include Entities in the Atom search results?
No, no plans for entities in the Atom representation.
Are there plans to include the full User object in JSON search results? We currently make batch calls to users/lookup to fill the gap, but we'd love to chop that out.
Much more long-term, when Search becomes part of the proper REST API on api.twitter.com and can share object structures with the REST API freely.
fine way to enroll any search via API
now, is it possible to find photos using the Search API? How is the best way to looking for therm (including "photo" or something like that in the query?) ??
