is not among

Type

operator

Summary

Evaluates to true if a chunk is not equal to any of the chunks in a string, false otherwise.

Syntax

<valueToFind> is not among the {paragraphs | sentences | lines | items | words | segments | trueWords | tokens | codePoints | codeUnits | bytes} of <stringToSearch>

Description

Use the is not among operator to find out whether a string does not exist as an entire word, item, or line of another string.

The valueToFind must be a single word, item, or line (whichever chunk type you have specified). If you specify a string containing more than one chunk, the is not among operator evaluates to true, even if all the chunks are in the stringToSearch.

The is not among operator is the logical inverse of the is among operator. When one is true, the other is false.
