What is the primary use of the WildMatch function?

The WildMatch function in Qlik Sense is primarily utilized to perform matching operations that involve wildcard characters. It allows users to match strings against patterns that include wildcards, such as asterisks (*) and question marks (?). This capability is especially useful for scenarios where you need to compare a string to multiple possible values in a flexible manner, accommodating various characters or substrings.

For example, if you have a list of product names and want to find all names that start with "Product" followed by any sequence of characters, WildMatch would allow for such flexibility. The use of wildcard characters is key, as it enables broader matching rules than strict or static comparisons.

This function is valuable when handling dynamic datasets where exact matches may not always be practical or possible. Hence, understanding how to leverage WildMatch with wildcards is essential for tasks involving pattern recognition or filtering datasets based on variable criteria.
