Latest Patents

One of Wang's latest patents is centered around reducing matching documents for a search query. The technology described in this patent provides a method for identifying matching documents using a bit vector search index. When a search query is received, a term is identified from the search index, and several bit vectors corresponding to that term are identified. Each bit vector comprises an array of bits, where at least one bit indicates that a corresponding document includes the term. Additionally, each bit vector contains other bits that indicate other documents include other terms. If it is determined that an unacceptable number of possible matching documents is likely to be returned, a strengthening row bit vector is selected to reduce the number of possible matching documents. The identified bit vectors and the selected strengthening row are then intersected to identify matching documents that contain the term.
