Index Constructing Method, Search Method, Device and System

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.

1. An index constructing method comprising:
constructing data obtained in each preset time period into a primary index segment, respectively, and merging the constructed primary index segment into a primary index segment set after each preset time period is over; copying each primary index segment in the primary index segment set and merging the copied primary index segments 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 search service; wherein the copying each primary index segment in the primary index segment set and merging the copied primary index segments into a corresponding large index segment specifically includes: copying each primary index segment in the primary index segment set in turn according to time sequence, and merging the copied primary index segments into the corresponding large index segment; wherein the corresponding large index segment is a large index segment which is in the large index segment set and neighbors a free memory.
