Not Equal to (<>) Operator
When configuring a search, the not equal to (<>) operator is one of the relational operators that lets you specify the relationship between an index field and an index value in your search criteria.
The not equal to (<>) operator is located in the Operator drop-down list, on the Search page.
Note: This list is not visible, until you select a document group and document type, and click the Add condition button, under the Search Criteria heading.
Use the not equal to (<>) operator to retrieve only those documents that do not contain, in the specified index field, the same index value as the one in the search phrase.
Customer Name <> Betty’s Music Store retrieves all documents with index values other than Betty’s Music Store in the Customer Name index field.
Ship Date <> 01/31/2001 retrieves all documents with index values other than 01/31/2001 in the Ship Date index field.
