There are a number of guidelines that you must observe when you use the NEAR operator condition in a rule.
If you combine a condition that uses a NEAR operator with one or more other conditions, you can join the NEAR operator condition to the preceding and following conditions with an AND logical operator only - not an OR operator. For example, consider the following rule:
Subject contains 'Symantec' AND Content Near 'Symantec Investment' AND MailDate = '17/03/2010' OR Importance = 'Normal'
You cannot insert an OR operator between the Subject and Content conditions, or between the Content and MailDate conditions. However, it is acceptable to insert an OR condition between the MailDate and Importance conditions.
When a rule contains multiple NEAR operator conditions, they must all use the same search attribute (Subject, Content, or SubjectOrContent). For example, in a rule that contains two NEAR operator conditions, you cannot set the attribute of one condition to Subject and the other to Content.
When a rule contains multiple NEAR operator conditions, and the search values that you specify are in different languages, the language of the first NEAR operator condition determines the language in which Discovery Accelerator conducts all the searches in the rule.
