Hi, I want to search a specific fields and do not know if the original is upper or lower case. A good example is email addresses which come in all kinds writing styles (e.g. firstname.lastname@example.org, john.DOE@example.com, John.Doe@example.com, ...).
A simple search for recipient:email@example.com should produce a hit on all of the above examples.
I have found that there is a field type called lowercase which sounds it might do the trick. Is this the way to go or do we need to do something else to achieve this?
