Searching for values might return unexpected results

In the expression editor, when searching for values for a data item, the results you obtain might contain unexpected results if the data item is not a string data type.

Because you can edit the expression for a data item, IBM® Cognos® Analytics cannot determine with certainty what the data type is.

Therefore, IBM Cognos Analytics guesses the data type of the data item by looking at its aggregate and rollup aggregate set.
