Computer document retrieval method

Abstract

The invention discloses a computer document retrieval method, and relates to distributed document storage equipment. In each piece of the distributed document storage equipment, the computer document retrieval method comprises the following steps: establishing a source document attribute database, establishing sub-database catalog tables of a first level, a second level, ...and an Nth level, retrieving documents, inputting retrieval key words into retrieval equipment, opening the retrieval catalog tables level by level, checking the source document attribute database, and feeding back the retrieval result to the retrieval equipment. The computer document retrieval method is applied to retrieval on a great number of documents in the distributed document storage equipment, documents can be flexibly checked according to different retrieval key words, the computer document retrieval method has the characteristics of rapid checking speed, high retrieval efficiency and flexible application, and the requirements of checking and positioning documents of different levels and types in the distributed document storage equipment, of a user, can be met.

Description

technical field [0001] The invention belongs to the field of computer file retrieval, and in particular relates to a computer file retrieval method. Background technique [0002] If the user wants to query one or a specific type of file in the computer, the current operating system provides a method to retrieve all files in the computer through the resource manager, which is time-consuming and inefficient. [0003] For users who have multiple file storage devices, such as USB flash drives, mobile hard drives, multiple computers, cloud disks, etc., if users want to find a specific file in their various storage devices, the resource manager provided by the operating system cannot retrieve files other than their own devices. Unless you connect this device to your own device through the communication system and use other devices as an extension of your own device, you can't do it; if you want to find a file in your circle of friends or colleagues' storage devices , for the same...

Problems solved by technology

[0002] If the user wants to query one or a specific type of file in the computer, the current operating system provides a method to retrieve all files in the computer through the resource manager. This method is time-consuming and inefficient.

[0003] For users who have multiple file storage devices, such as USB flash drives, mobile hard drives, multiple computers, cloud disks, etc., if users want to find a specific file in their various storage devices, the resource manager provided by the operating system cannot retrieve files other than their own devices. Unless you connect this device to your own device through the communication system and use other devices as an extension of your own device, you can't do it; if you want to find a file in your circle of friends or colleagues' storage devices , for the same reason, it cannot be done, let alone find files in a larger range

[0004] There is also file retrieval software, which uses the method of building index files for all selected types of files in a computer to achieve the purpose of fast retrieval and query of files in this computer, but only the computer where the file retrieval software is located can achieve this function , unable to achieve the goal of fast query for a wider range of computers
