Since the last upgrade, the search function of the forum software is working way better. And it now works better than Google Custom Search for drilling down in specific forum categories, dates and user names.
Click on "Search" on the forum menu bar next to "Active Threads"
On the Search page, select the forum section you want
On " Keyword Search Terms" type in a word or two from the post you want to find
Optional to put a public user name in the box for "By Display Name"
Select a date range of the 4 years when your post was made
Click the "Search" button.
You'll see a list of posts from the time period, keywords and forum section you selected.
See attached screenshot of Search page.
Let me know by PM message if you have trouble.
