Consider the following scenario:
Additionally, you experience poor performance when you visit a Commerce Server site that uses the CampaignItemManager.Search method.
Note The Contains member tests whether a property contains the value of a specified argument.
This issue occurs because the Contains member maps to the LIKE operator in the Transact-SQL statement. This behavior causes the poor performance of the SQL query that is generated when the CampaignItemManager.Search method is called.
After you apply the hotfix, a new member is added to the ExplicitComparisonOperator enumeration under the Microsoft.CommerceServer namespace. This new member is the ContainsItem member. The ContainsItem member tests whether a property contains the value of a specified argument. The ContainsItem member maps to the CONTAINS operator in Transact-SQL.
Additionally, a new full-text index is created in the mktg_creative_property_value table of the marketing database. Therefore, when you use the CampaignItemManager.Search method on a Commerce Server site together with a ContainsItem member to construct a search statement, the performance is improved.
