Examples:

111\d-\d{4}-\d{4}-\d{4}, where \d stands for any number from 0 to 9. This regular expression excludes from category-based scanning the sequences of symbols 1113-3333-3333-3333.
colou?r, where u? stands for the letter u that does not appear in the sequence of symbols or appears in it only once. This regular expression excludes from category-based scanning the sequence of symbols color and colour.
The application does not consider the case of symbols used in the regular expression.
