  • Patent number: 9576054
    Abstract: A search method is disclosed. In the method, a data rewriting system obtains, from a database, one or more search term candidates that are relevant to a present search term. The data rewriting system retrieves properties of the present search term and the one or more search term candidates, where the properties describe respective matching results of the present search term and the one or more search term candidates. Based on the matching results, the data rewriting system determines whether the present search term needs to be rewritten, and rewrites the present search term based on the matching results to provide a rewritten present search term in response to determining that the present search term needs to be rewritten. A search engine performs a search based on the rewritten present search term.

  • Publication number: 20160339457
    Abstract: A water outlet valve core of a wall mounted shower head and a water output device each includes an inlet, two outlets, an annular channel, and a flow channel. Water enters the water outlet valve core through the inlet, and most of the water passes through the flow channel and flows out of the outlets. The remaining water passing through the flow channel then enters the annular channel, and is mixed with the most of the water out of the flow channel to flow out of the outlets. Based on concepts of jet switching within a same element, strong water flow and weak water flow switch alternatively to implement the effect of hydro massage, such that conventional rotor-type shower heads won't be easily stuck or worn out to cause loss of massage functions.
