What are regular expressions?
🔍 One regular expression is a search pattern.
It is not a matter of simple letters or words, but rather of sequences of symbols and characters representing more complex conditions.
For example, with a pattern you can tell Google Docs to look for all words beginning with a capital letter o all numbers of a document.
Does Google Docs support regular expressions?
The answer is yes.
Although Google Docs does not have as full support as specialized text editors, its Search and replace includes the option "Match regular expression".
With that box checked, you will be able to perform much more refined searches.
