How do I get around case sensitivity for glossary terms?

Firstly, I'm confused by your conflicting instructions. On the glossary management page in my account (/v1.0/glossary-definitions), the page description reads:

"To use, type phrase in your documentation"

It doesn't say anything about case sensitivity, so I was surprised to discover recently that when a term entered as "Withdrawal" is referenced in a doc as withdrawal, it is omitted from the customer view of the page.

Then I came across this example in the documentation:

Both GLOSSARY:EXOGENOUS and GLOSSARY:ENDOGENOUS are long words.

Which displays the words in lowercase. Great!

However, when I tried that myself, using GLOSSARY:MAINNET in a doc, in the hope of it retrieving my definition for mainnet, it shows up as:

"The functionality described on this page is not yet available on GLOSSARY:MAINNET."

Do I have to create duplicate glossary entries to accommodate both upper and lowercase usage of the term?
