The Contain Filter
The Contain Filter element is used with datalayer elements to filter out data rows. It's analogous to using a WHEREx CONTAINS y clause in a SQL query but, unlike a query, it's applied to the data after it's been retrieved into the datalayer.

About the Contain Filter
The Contain Filter element is available for use with all datalayer elements and is particularly useful in conjunction with those lacking query capabilities,such as DataLayer.XML and DataLayer.Web Service.
In operation, the element basically searches a specified data column valuefor a specified text string and removes all rows from the datalayer where the string is not found in the column.
This element is similar to element, however, it frequently provides better performance because it's implemented as a native part of the Logi Data Engine and so does not need to execute script, asthe Condition Filter does.
