Features

• Interactive menu
  six menu items covering list generation, JSON search, file search, history, and settings

  exact substring, fuzzy (configurable threshold), word stems, and regular expressions
• 6 document types
  PDF (text-based and image/OCR), JPG/JPEG, DOCX, XLSX, PPTX, ODT, and TXT
• OCR support
  reads text from JPG images and image-based PDFs via Tesseract; configurable language, PSM, DPI, and confidence threshold
• Fuzzy matching
  sliding-window algorithm catches typos and OCR artefacts; default similarity threshold 80 %
• Stems mode
  searches word stems to match inflected forms; configurable minimum stem length
• Filelist comparison
  compare a plain-text list of filenames against filenames.json; generates a PDF report and an optional hitlist (.txt)
• Hash list matching
  compare external SHA-256/MD5 hash lists against filenames.json; supports NSRL RDS CSV format; recursive hashes/ directory scan
• File export
  copy all hash-matched files into a structured export/ directory with associated reports
• Highlight & mark
  matches are annotated directly in output copies (PDF highlight annotations, [[FOUND]] markers in TXT, copied files for JPG and Office formats)
• Per-file PDF reports
  match breakdown with file metadata, hash verification, context snippet, and a forensic disclaimer
• CSV summary
  semicolon-delimited, timestamped export of all search results (UTF-8 BOM for broad tool compatibility)
• Settings editor
  runtime editing of all parameters; changes are saved to txtfinder_config.json and loaded automatically on startup
• Disk text cache
  extracted PDF and OCR text is persisted to .txtfinder_cache/ with automatic 90-day cleanup
• In-memory text cache
  extracted text is reused within a search run to avoid double-processing (FIFO eviction, 200-entry limit)
• Search profiles
  extra search words can be saved as reusable profiles and loaded before each run
