    searcher, hyperscan, etc.
  - Multi-threaded search using high-performance lock-free job queue stealing
  - Multi-threaded task-parallel decompression and search
  - Optimized pattern matching (AVX, SSE2, ARM NEON/AArch64)
  - Optimized asynchronous IO for efficient concurrent searching
  - Thoroughly tested (includes over 1000 test cases)
  - Compatible with the standard GNU/BSD grep command-line options

  - Search compressed files (zip, gz, Z, bz, bz2, lzma, xz)
  - Search pdf, doc, docx, xls, xlxs, and more using filters
  - Search binary files and display hexdumps with binary pattern matches
  - Search UTF-encoded files with Unicode pattern matches (by default)
  - Search files encoded in ISO-8859-1 thru 16, CP 437, CP 850, MAC, KOI8, etc.
  - Search files excluding files specified by .gitignore etc.
