The Boolean operator "NOT"

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’.

Example 2 : if you enter the following query:

Text’O’Mat finds the greysed documents that contain the term ‘invoice’ without the term ‘estimate’.
