Abstract

The invention discloses a data retrieval method and device and a server, and belongs to the field of data retrieval. The method comprises the steps of determining an identifier of a relational user according to an identifier of a retrieval user; inquiring an identifier of a data object corresponding to the relational user according to the identifier of the relational user; retrieving a target object according to the inquired identifier of the data object corresponding to the relational user; outputting the target object to be used as a retrieval result. According to the data retrieval method, the identifier of the relational user with the specific type relation with the retrieval user is determined, the identifier of the data object corresponding to the relational user is inquired, and the target object is retrieved according to the inquired identifier of the data object corresponding to the relational user, so that the problem that in the prior art, when a network community comprises a large number of data objects of a keyword, a server needs to consume a large number of processing resources and bandwidth resources when outputting the retrieval result is solved, and the purpose of improving the system performance is achieved.

Description

technical field [0001] The invention relates to the field of data retrieval, in particular to a data retrieval method, device and server. Background technique [0002] With the continuous development of Internet applications, online communities, such as blogs or forums, have gradually become an important part of many people's daily lives. In the process of using the online community, users often need to retrieve data objects containing specific content, such as searching logs containing keywords. [0003] In the existing data retrieval method, the server obtains each data object in the network community in advance, and builds an inverted index for each data object, and the inverted index includes the correspondence between each keyword and the data object containing each keyword relationship; when the server receives the retrieval request sent by the user, it will directly retrieve all data objects containing the keyword from the inverted index according to the keyword carr...
