Hi @ERCPRATIK ,

You can use the search term  “!yourkeyword*” similar to a not like operator. ‘! ‘represents not equal and ‘*’ represents the wildcard which substitutes one or more character. Also, you can use ‘+’ operator to combine with multiple keywords.

i.e. “!keyword1* + !keyword2*”

Below example shows the search result for tasks which do not start the place_ids from “A2” keyword.
