    摘要： The present disclosure discloses an index constructing method, search method, device and system. The index constructing method includes: constructing data obtained in each preset time period into a primary index segment, respectively, and merging the constructed primary index segments into a primary index segment set after each preset time period is over; copying and merging each primary index segment in the primary index segment set into a corresponding large index segment, to obtain a large index segment set; and sending the primary index segments in the primary index segment set or the large index segments in the large index segment set to a search device to provide a search service. The present disclosure constructs the primary index segments on the basis of time, merges the constructed primary index segments into the large index segment, and provides the search service simultaneously with the primary index segments or the large index segments, thus, improving search speed.

    摘要翻译： 本公开公开了索引构造方法，搜索方法，装置和系统。 索引构造方法包括：将在每个预设时间段中获得的数据分别构建成主索引段，并将构造的初级索引段合并成每个预设时间段之后的主要索引段; 将主索引段中的每个主索引段复制并合并到相应的大索引段中，以获得大的索引段集合; 并将主要索引段集合中的主索引段或大索引段中的大索引段发送到搜索设备以提供搜索服务。 本公开基于时间构建主索引段，将构建的主索引段合并到大索引段中，并且与主索引段或大索引段同时提供搜索服务，从而提高搜索速度。
