Samsung patents faster data lookup using cached search history

Samsung describes a method for electronic devices to find data faster by checking a small, fast memory area called a main cache before looking at slower storage. If the search term matches past activity stored in the cache, the device retrieves the data from quick memory; otherwise, it checks the hard disk and main memory.

Why it mattersThis improves how devices manage storage speed, which can make phones and computers feel more responsive when opening files or apps.

In the filing’s own words

Disclosed are a data query method, a data query device, a storage device, and an electronic device. The data query method comprises: receiving a data query request carrying a keyword associated with data to be queried; querying the keyword in the main cache, wherein ordered views that have been accessed historically are stored in the main cache and each of the ordered views comprises a plurality of historical keywords; in a case that a historical keyword matching the keyword is not found in the main cache, querying the data corresponding to the keyword in the hard disk and the memory based on the keyword and obtaining the data to be queried; and in a case that a historical keyword matching the keyword is found in the main cache, querying the data corresponding to the keyword in the memory based on the keyword and obtaining the data to be queried.

What exactly they claim (claim 1)

1. A data query method, wherein the data query method is applied to a storage device comprising a memory, a hard disk, and a main cache, the data query method comprising: receiving a data query request carrying a keyword associated with data to be queried; querying the keyword in the main cache, wherein ordered views that have been historically accessed are stored in the main cache and each of the ordered views comprises a plurality of historical keywords; in response to a historical keyword among the plurality of historical keywords matching the keyword not being found in the main cache, querying the data corresponding to the keyword in the hard disk and in the memory based on the keyword and obtaining the data to be queried; in response to the historical keyword matching the keyword being found in the main cache, querying the data corresponding to the keyword in the memory based on the keyword and obtaining the data to be queried, in response to content of the memory being written to the hard disk, obtaining a proportion of specific keywords to all keywords in the memory, wherein the specific keywords are other keywords that are not present in the hard disk, and in response to the proportion exceeding a first threshold, marking specific ordered views corresponding to the specific keywords with a collection mark in the main cache, and updating the data corresponding to the other keywords in the memory other than the specific keywords to the main cache.
