The present disclosure provides a method and apparatus for pushing search results, an apparatus and a non-volatile computer storage medium. The method comprises: performing real-time search according to the user's key word to obtain current search results; performing statistics of access heat of each content in the current search results; obtaining, from the current search results, content whose access heat meets heat requirements, as content to be pushed; pushing the content to be pushed to the user. According to the present disclosure, while the real-time search is implemented, the search results are screened according to the access heat, which facilitates reduction of the number of search results pushed to the user, and thereby reduces network resources consumed in pushing the search result to the user.
