You cannot use regular expressions with the Find in Files feature.
| Regular Expression | Description |
| . | Any single character. |
| [ ] | Any one of the characters contained in the brackets, or any of an ASCII range of characters separated by a hyphen. For instance, b[aeiou]d matches bad, bed, bid, bod and bud. x[0-9] matches x0, x1, x2, and so on. If the first character in the brackets is ^ (caret), then the regular expression matches any characters except those in the brackets. Bracketed characters followed by a + (plus) match one or more of the bracketed characters so that r[eo]+d matches red, rod, reed, and rood as well as reod, rooed, and roed. |
| ^ | The beginning of a line. |
| $ | The end of a line. |
| ( ) | For Find, the sequence of characters between the parentheses will be matched. For instance, (ju)+fruit finds jufruit, jujufruit, jujujujufruit, and so on. Note that it will not find jfruit, ufruit, or ujfruit because the sequence ju is not in any of those strings. |
| (c|c) | Any one of the characters separated by the alternation symbol (|). For instance, (j|u)}+fruit finds jfruit, jjfruit, ufruit, ujfruit, uufruit, and so on. |
| * | None or more of the preceding character or expression. For instance, ba*c matches bc, bac, baac, baaac, and so on. |
| + | At least one or more of the preceding character or expression. For instance, ba+c matches bac, baac, baaac, but not bc. |
| [^ ] | Any character except those following the ^ character (caret) in the brackets, or any of an ASCII range of characters separated by a hyphen. For instance, x[^0-9] matches xa, xb, xc, and so on, but not x0, x1, x2, and so on. |
| \e | Predefined expression, where \e can be: |
| \d | Any decimal digit. |
| \n | End-of-line. |
| \w | Any alphanumeric character. |
| \ | Disables the pattern match characteristic in the Find What box from the special characters listed above. For instance, 100$ matches 100 at the end of a line, but 100\$ matches the character string 100$ anywhere on a line. |
