Problems solved by technology

[0004] First of all, relying on the performance of the server on the network side, the online search engine can process a large amount of index data at one time when searching. When it is large, it needs to be split into multiple index files for storage, and each search needs to traverse all index files, which affects search efficiency
Moreover, in addition to affecting performance, due to limited storage space, user devices (especially mobile user devices such as mobile phones and tablets) are more sensitive to the size of index files. It will lead to a rapid increase in the size of the index file, which will affect the use of other functions on the device

Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only It is a part of the embodiments of this application, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application shall fall within the protection scope of this application.

[0033] First, a brief introduction to the basic principles of search engine indexing:

[0034] After the user inputs a search keyword, what the search engine needs to do is: find a document containing the keyword (or information related to the keyword), and generate a search result to feed back to the user. The "document" here is a general term for search objects, and in different sear...

Abstract

The invention discloses a search engine index construction method and apparatus. The search engine index construction method comprises the steps of performing segmentation processing on a text string in a document to obtain corresponding text substrings; according to a preset feature extraction rule, determining a feature of each text substring; and for any text substring, writing index information of the text substring in an index file taking the feature of the text substring as an identifier. By applying the scheme, the search efficiency can be effectively improved.

Description

technical field [0001] The present application relates to the field of search technology, in particular to a method and device for constructing a search engine index. Background technique [0002] Local search refers to the search performed on devices such as PCs and mobile phones for the content stored locally on the device. With the improvement of user needs, the local search function is not limited to finding documents with a specific name, but can search for the content inside the document, such as finding word files, PDF files, text messages, emails, etc. that contain specific characters. [0003] Similar to the principle of searching webpage content, in order to achieve fast search of local document content, it is necessary to build index information for the content appearing in the document, and the existing local search engines generally build indexes in the way of online search engines . However, in practical applications, the operating environments of local searc...
