  • Publication number: 20200301974
    Abstract: A client instance provides search suggestions based on a partial search query. The search suggestions include user search suggestions based on previous search queries performed by the user and instance search suggestions based on previous search queries performed on the instance. The client instance filters the instance search suggestions based on filter criteria associated with the user, such as an interface used by the user, a search context, user group that the user belongs to, domain used by the user, and so on. The client instance may remove the search suggestions that include blacklisted terms. The client instance may rank the search suggestions (e.g., based on frequency and/or recency) and enable the user to select those ranked search suggestions that meet or exceed a threshold.

  • Publication number: 20200048409
    Abstract: Disclosed is a method for preparing polylactone by ring opening, belonging to the technical fields of organic catalysis and polymer materials. The invention proposes a new catalytic mechanism, wherein an organic alcohol is used as an initiator to initiate ring opening polymerization of a cyclic monomer under the catalysis of an organic catalyst to obtain a polylactone; and the catalyst is a pyridinium salt. The present invention has the advantages of non-toxic reaction, simple conditions and controllable process; further, the invention can obtain a narrow molecular weight distribution in the absence of solution polymerization, and can effectively inhibit the occurrence of the transesterification compared with the catalysis of 4-(N,N-dimethylamino)pyridine.
