Examples showing the use of Operands
The following examples show how operands can be inserted and how RiskFilter will use them to decide
whether to trigger the action defined in the Advanced Content Filter:
RiskFilter <AND> Gateway <AND> Innovation
This expression matches content when “RiskFilter”, “Gateway” and “Innovation” are all present.
RiskFilter <OR> Gateway <OR> Innovation
This expression matches content when “RiskFilter”, “Gateway” or “Innovation” is present.
<OCCUR> gateway
(Assume Frequency =2 )
This expression matches content if “gateway” occurs more than twice.
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
