The logical (boolean) operators, which define the relationships between condition rows on the same level, have a various priority. It affects the evaluation of the whole complex condition to a great extent. A user should take this into account when defining a condition in the Expert Search.

Example:

• A and B or C and D

  First the "A and B" and "C and D" conditions (before the "OR" operator) are processed, then the OR operator is evaluated.

The AND operator always has a higher priority than OR. The NOT operator (negation) has the highest priority.

If you want the priority to be changed within the structure of the Expert Search, you must use parentheses and create condition subqueries.
