  • Snippet generation system
    Patent number: 11797587
    Abstract: Systems and methods are provided for generating a rank vector comprising an array of values for each term position of a document and setting a value at a position of each term identifier in the document to a distance score for each term identifier, calculating snippet frame quality scores for each frame of a plurality of frames in the rank vector, determining whether a length of the character string associated with the frame with the highest frame quality score is similar to a requested length for a snippet, if necessary, adjusting the size of the character string to be similar to the requested length for the snippet and, once the length of a character string for one or more frames is similar to the requested length for the snippet, generating the character string to be provided as a snippet.

  • Fast substring fulltext search
    Patent number: 9965546
    Abstract: A system includes receiving a substring to be searched and determining one or more N-grams associated with the received substring. A lookup of each of the one or more N-grams is performed using an N-gram index. A set of tokens associated with each of the one or more N-grams is calculated and a determination is made if the substring exits in the calculated set of tokens. The results of the determination if the substring exits in the set of tokens are outputted.
