less than or equal to, on or before
The symbol for the less than or equal to operator is <=. It specifies that the value of the property stored in the FileNet library must be less than or equal to the comparison value that you enter in the search condition.
For example, if you enter a condition such as
name <= Brown
you will get the value Brown and all values that precede Brown alphabetically (in ASCII order).
When you search on a date property in an IDM Image Services library, the less than or equal to operator appears in grid view as "on or before."
