INFORMATION BY THE KEYWORDS SEARCHING DEVICE Russian patent published in 2019 - IPC G06F16/13 

FIELD: information technologies.

SUBSTANCE: invention relates to the users on the Internet search query processing information systems. Technical result is achieved due to the information searching device by the keywords, used on the server and including a key in the alphabetical classifier searching module, prefix combinations tree (PCT) module generation, which is designed with possibility of the key array initial processing performance for the PCT obtaining and the prefix combinations corresponding frequencies determining, by which it determines the number of keys in the class for the given key prefix, prefix frequencies counting module, operations in the alphabetical classifier (AC) total number counting module, “n_max” and “n” optimal parameters result selection module and the optimal AC generation module, at that, through the prefix combination tree (PCT) containing database, the said prefix combination tree (PCT) generation module is connected to the operations in the alphabetical classifier (AC) total number counting module, which, in turn, is connected to the said “n_max” and “n” optimal parameters result selection module, wherein the latter is connected to the optimal AC generations module.

EFFECT: enabling the key in the key array quick searching by minimizing the number of steps for transition to the desired key.
