Multiple operators can be used in a single keyword expression, but multiple operator types are not allowed in a single dynamic keyword expression.
For example: RiskFilter<OR>Gateway<AND>Innovation is an invalid keyword expression. Valid keyword expression examples:
•RiskFilter
•innovation
•RiskFilter <AND> innovation
