Abstract: Embodiments of the present invention relate to the field of computer technologies, and provide a search method and apparatus to resolve a problem that a reference text, of a text in a professional field, that is determined by using the prior art has relatively low accuracy. The method includes: obtaining n named entities in a current to-be-analyzed target case (S300); determining a first characteristic and a second characteristic (S301); generating, based on the first characteristic and the second characteristic and according to a preset vector generation rule, a target characteristic vector corresponding to the target case (S302); obtaining each historical case in a database and a characteristic vector corresponding to each historical case (S303); and separately calculating a similarity between the target characteristic vector and the characteristic vector corresponding to each historical case, and selecting a historical case whose similarity result meets a preset condition as a reference case (S304).

Abstract: A support assembly, includes a rotating shaft mechanism and a support portion. The rotating shaft mechanism includes a rotating assembly. The rotating assembly includes a first fastening piece, a second fastening piece, a connecting piece, and a connection rod assembly. The first fastening piece and the second fastening piece are located on a same side of the connecting piece. A first sliding slot is disposed on an end face that is of the first fastening piece and that faces the second fastening piece, and a second sliding slot is disposed on an end face that is of the second fastening piece and that faces the first fastening piece. The support portion includes a first support board, a second support board, and a third support board. The second support board is rotatively connected to the first support board and the third support board.
