Match case and whole word
Match case is off by default, so a search for “draft” also matches “Draft”. Turn it on when capitalization matters. Whole word is also off by default; turn it on to prevent a short term from matching inside a longer word.
Whole-word boundaries recognize Unicode letters and numbers, so searching for “ação” does not match inside “reação”. Underscores also count as part of a word.
Example input
Ação e reação. ação!
Result
With Whole word on and Match case off, “ação” matches “Ação” and the final “ação”, but not the letters inside “reação”.
