How is it used?
Add Text Filter Refine Parsed Results Change Capitalization
The Change Capitalization filter comes with three options. The first “Capitalized Case” updates the text so that the first letter of each word begins with a capital letter. The second option “All UPPER Case” switches all text to upper case and the third option “All lower Case” does the reverse of converting all text to lower case.
