ServiceNow performs conjunction
statements before disjunction statements in a query.
When you create a complex query, you must use parenthesis around disjunctions where appropriate
to ensure proper grouping of query elements. For example, you must use parenthesis in the query
(md_table = 'incident' || md_table = 'task') && mi_definition = md_sys_id
&& mi_id = inc_sys_id. Removing the parenthesis from this query returns all
records where the md_table value is incident.
