FAQ
What are regular expressions?
Regular expressions are a powerful language for pattern matching. For example, '\d+' matches one or more digits, and '[A-Za-z]+' matches one or more letters. They enable complex search and replace operations.
What's the difference between case-sensitive and case-insensitive?
In case-sensitive mode, 'Hello' and 'hello' are treated as different strings. In case-insensitive mode, they are treated as the same. Enable case-insensitive for general document searches.
What does whole word matching mean?
Whole word matching only matches complete words. For example, searching for 'test' will not match 'testing'. Useful when searching in languages with word boundaries like English.
What can I do with regular expressions?
Regular expressions enable advanced replacements like standardizing phone numbers, extracting specific date formats, converting HTML tags, and more.
