The
operator discards the documents what contain the terms that follow it.
Used without parentheses, this operator takes action on the whole
rest of the line.
Text’O’Mat
leaves out the documents that contain the term(s) after the NOT operator.
Example
1 : if you type the query:
'NOT
estimate'
Text’O’Mat
only retrieves the greysed documents that do not contain the word ‘estimate’.
