Less Than or Equal to (<=) Operator
When configuring a search, the less than or equal to (<=) operator is one of the relational operators you can use to specify the relationship between an index field and an index value in your search criteria.
The less than or 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 less than or equal to (<=) operator to retrieve only those documents that contain, in the specified index field, an index value that is less than or equal to the one in the search phrase.
Ship Date <= 07/01/2001 retrieves all documents with an index value of 07/01/2001 or earlier in the Ship Date index field.
Invoice Amount <= 15000 retrieves all documents with an index value of 15,000 or less in the Invoice Amount index field.
