When using the Advanced Search feature in DocuShare the "Contains" function behaves as an "Is" function when searching for values stored as an Integer type property. For example creating a search query for a custom integer property labeled Quantity that "Contains" the value 50, will return results that match 50. Objects with Quantity property values containing 50, such as 500, will not be returned. The expected behavior to find any object where the Quantity property value contains 50 such as 500, 1050, 5099 . . . will not be returned in the search results. This is a known limitation in DocuShare 3.1.
