Less Than (<) Operator
When configuring a search, the less than (<) 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 (<) 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 (<) operator in a search to retrieve only those documents that contain, in the specified index field, an index value that is less than the one in the search phrase.
Ship Date < 06/01/2001 retrieves all documents with an index value of 05/31/2001 or earlier in the Ship Date index field.
Invoice Amount < 20000 retrieves all documents with an index value of 19,999.99 or less in the Invoice Amount index field.
