Negation [^]
Summary
[^] negates a single character and/or range that is contained within the brackets. Literal characters and ranges can be mixed. If the caret symbol (^) is not placed at the start, the search engine will search for occurrences of the symbol itself. However, the ^ symbol is by default not included in the character set and will not be found. If you want to be able to search on the ^ symbol, please contact support (http://zylab.support.com).

[a^bc] |
