Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0031] figure 1 It is a search method provided by the embodiment of the present invention. like figure 1 As shown, the search method may include the following steps:

[0032] Step 101: Obtain the target search term.

[0033] The embodiments of the present invention relate to a search method, so when performing a search, it is necessary to obtain a target search word for searching. Wherein, the target search term is the text information input by the user, such as "video tutorial of machine learning algorithm", "video tutorial of word application" and so on.

[0034] Step 102: Perform word segmentation processing on the target search word according to the pre-established word segmentation database, and obtain a first word segmentation result.

[0035] The words in the thesaurus are target words extra...

Abstract

Embodiments of the invention provide a search method and apparatus, an electronic device and a computer readable storage medium. The method comprises the steps of obtaining a target search term; according to a pre-established word segmentation library, performing word segmentation processing on the target search word to obtain a first word segmentation result; searching data matched with the firstword segmentation result in a pre-established database; wherein words in the word segmentation library are target words extracted from historical search records of a user in a machine learning mode,and the target words are used for describing search targets of historical search words. Therefore, according to the scheme, the problems that based on an existing word segmentation method, when searching is carried out, the searching time is long, and the searching result accuracy is low can be solved to a certain extent.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a search method, device, electronic equipment and computer-readable storage medium. Background technique [0002] An information flow background, which provides a search of the whole library of short videos based on Elasticsearch (that is, a search server based on Lucene (search engine), in which users can search by video ID, video title, etc. However, based on the default Chinese word segmentation algorithm of Elasticsearch, not only the matching results may not be very accurate, but also many of the matching results may not be what the user really needs. Returning too many results will also take a long time, and the user experience is very bad. it is good. For example, if a user searches for "machine learning algorithm video tutorial", it should not return results containing only "machine" or only "learning" or only "algorithm", but must contain the entire word "mach...
