What determines the proximity of EDM tokens to be considered a match?

Resolution

QUESTION

If I am looking for 2 elements, like Name and SSN, in a EDM, what is the Symantec DLP parameter that says how far apart in a document they can be, to be a match?

ANSWER

The following settings within the Advanced Server Page determine the proximity of EDM tokens.

EDM.RunProximityLogic 
If this value is true, then it runs the token proximity check. The free-form (a.k.a. simple) text proximity is defined by EDM.SimpleTextProximityRadius setting. The tabular text proximity is defined by belonging to the same table row. If EDM.RunProximityLogic = false it will check the entire document for matching.  If EDM.RunProximityLogic = true it will only match within the proximity range

EDM.SimpleTextProximityRadius 
This is the number of tokens to the left and to the right of the current token that are evaluated together when the proximity check is enabled.
