US Patent 10,552,490

  • Title: Methods and systems for search indexing
  • Assignee:
    • Current: X1 Discovery Inc
    • Original: FUTURE SEARCH HOLDINGS Inc
  • Inventors: William Gross, Steven Lee Colwell
  • Filing Date: April 24, 2017 (for application number US15/495,507)
  • Issue Date: February 4, 2020
  • Abstract: The patent describes systems and methods for quick and efficient searching. One embodiment involves receiving two search strings entered into the same search field and incrementally locating documents where a first word begins with the first string and a second word begins with the second string.

Independent Claims Overview (based on embodiments described in the patent's Summary section, as the full claims section was not provided):

  1. Method for Incremental Multi-String Search: This embodiment outlines a method where a system receives at least two search strings as they are being entered into a single search field. The system then incrementally finds documents that contain at least a first word starting with the first search string and a second word starting with the second search string.
  2. Search Apparatus for Incremental Multi-String Search: This describes a search apparatus with instructions to read at least two search strings from the same search field. It then incrementally filters search results to locate documents where a first word begins with the first string and a second word begins with the second string.
  3. Search Index System with Punctuation Handling: This embodiment covers a search index system. It includes scan code to determine files for indexing and index code to perform the indexing. The index code is further configured to identify punctuation marks in a search string and treat some of these marks as string separators based on their position within the string.
  4. Method for Selective Search or Command Execution: This method involves receiving a string in a search field, determining if it is a command, and then either initiating command execution if it is a command or initiating a search if it is not.
  5. Search Apparatus for Selective Search or Command Execution: This apparatus includes instructions to receive a string in a search field, determine if it corresponds to a command, and then either execute the command or initiate a search based on that determination.
