Dotted TOC leaders preserve word spaces for phrase search (#3086), while short tracked ellipses remain intact and searchable; sparse lines and condensed OCR gaps below the existing height-based threshold remain limitations. Complex interleaved flows still use a geometric reading-order heuristic. Soft hyphens, zero width spaces and joiners, word joiners and U+FEFF inside a word are skipped, in the page and in the query; a skipped zero width space still ends a word for Whole words only. A line break reads as no word break when the line ends in a soft hyphen, or when it runs on between two Chinese or Japanese characters (East Asian Wide, Fullwidth or Halfwidth, not Hangul and not fullwidth Latin letters or digits), so a divided word is found, in horizontal lines and in vertical columns that continue to the left; the break stays a space beside Latin or Korean text and between text set side by side on one line or in staggered cells."
