Use the search function, in the navbar. Just below the word Aussie in aussiehomebrewer in the board logo.
Put the word invert in there.
Search.
You end up with four pages, with at least 3 topics that cover invert sugar. Some of these then contain very interesting explanations and links to other sites.
Rather than starting a new topic, do a search, and append your question to an existing thread. This way you gain a much broader understanding and the forum doesn't end up with the same topic every 6 months.
