METHOD AND APPARATUS FOR SEARCH

摘要

Methods and apparatuses for search are provided and related to the field of search technology. A method may include: performing term segmentation for grabbed documents to count a term frequency of each term, the term frequency of the term representing a number of the grabbed documents containing the term; generating a high frequency term inverted index and a low frequency term inverted index respectively, wherein the high frequency term inverted index contains terms having a term frequency higher than a predefined threshold, and the low frequency term inverted index contains terms having a term frequency not higher than the predefined threshold; and loading the high frequency term inverted index and the low frequency term inverted index respectively to different retrieval modules, the different retrieval modules respectively corresponding to mutually independent storage devices.
