METHOD FOR ORGANIZING THE SEARCH FOR DOCUMENTS IN APPLIED UNSTRUCTURED DATA BASES AND A HARDWARE VERSION OF DUAL MEMORY FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G06F16/93 G06F12/06 

FIELD: computer engineering.

SUBSTANCE: auxiliary tables are formed: keywords, documents, binary strings of document numbers and binary strings that complement the inverted index. After selecting the lists by keywords from the inverted index, the lists of documents presented as binary strings are processed in the resulting list processing block. In this case, binary strings are loaded for processing into dual memory, in which the numeric value of the string (memory register) is equal to 2ⁿ. In the block for processing document pages, a response table is formed for each document by keywords. Dual memory is a logical memory circuit and contains data input channels, an SM input, switching the operation of the circuit from conventional memory mode to dual memory mode, a block for addressing bit numbers in memory cells, a switch, logical switches. The output of the write/read control block CS, RD, OE is connected to the output of the bit number selection block (column address).

EFFECT: simplifying and accelerating the procedure for searching for documents in accordance with the specified criteria.
