Embodiment Construction

[0020] Such as figure 1 As shown, an efficient search method for embedded devices includes the following steps:

[0021] Step 1: Create a search assistant and apply for a search buffer in it; the buffer is used to save search results and last search keywords;

[0022] Step 2: The caller requests a search keyword from the search assistant;

[0023] Step 3: The search assistant conducts a full-range search at the source data, copies the search results to the buffer, records the last search keyword in the buffer, and saves the preset number of keywords in the search results The record returns presented to the caller;

[0024] Step 4: When the caller continues to request search keywords from the search assistant;

[0025] Step 5: The search assistant detects and judges whether the search is based on the last keyword, if yes, then go to step 6; if not, go to step 3;

[0026] Step 6: The search assistant directly clears the unqualified search results from the buffer, records the...

Abstract

The invention provides an efficient search method of embedded equipment. The method comprises the following steps: establishing a search assistant and applying a search buffer in the search assistant; asking for a search key word from the search assistant by an invoker, performing once total-range search on source data by the search assistant, copying search results to the buffer, recording the search key word of the last time, returning preset quantity of records and presenting the returned records to the invoker; when the invoker continuously asks for the search key word from the search assistant and if the search assistant inspects that search is performed on the basis of the key word of the last time, directly removing the search results which do not meet the conditions from the buffer, recording the search key word of the last time, returning preset quantity of records and presenting the records to the invokers; and if the search assistant inspects that the search is not performed on the basis of the key word of the last time, performing once total-range search on the source data again. By applying the search method provided by the invention to the embedded equipment, efficient search is realized.

Description

technical field [0001] The invention relates to an efficient search method for embedded devices. Background technique [0002] Embedded equipment is mainly composed of embedded processors, related supporting hardware and embedded software systems. It is a "device" that integrates software and hardware and can work independently. Embedded processors mainly consist of a single-chip microcomputer or microcontroller (MCU). Relevant supporting hardware includes display card, storage medium (ROM and RAM, etc.), communication equipment, IC card or credit card reading equipment, etc. The embedded device system is different from the general computer processing system. It does not have a large-capacity storage medium like a hard disk, but most of them use flash memory (Flash Memory) as a storage medium. [0003] At present, the embedded devices on the market basically have the search function. For example, for the search of the address book, there are mainly three search methods: th...
