When defining the key words or phrases that you want a trigger to detect, you can use variables to represent certain types of information. You can also use 'unknown text' variables to save as-yet-unknown text as a searchable attribute of a captured file, Web or email event.
A wide range of variables are available, providing great flexibility when defining your search text. For example, you can use the %DIGITS% variable to detect any sequence of digits such as a credit card number or telephone number. Other variables force the trigger to consider the context in which an item of text occurs. For example:
%+URL% unipraxis
This expression only matches against 'unipraxis' if it appears as part of a URL, such as in www.unipraxis.com.
Buy %number% units at %money% each
This expression matches phrases such as 'Buy 100 units at $34.45 each' and 'Buy 2000 units at £20' each.
Note: You can also use 'search text' variables when defining Parameter 7 in a document classification.
