I don't have a moho but wanted to comment on the search system.
I agree searching using the site:airforums.com method is very useful. But don't give up on using the search feature on the Air Forums site. Notice when you drop down the choices under the search tab there are several options.
The method I find most useful is to put the words you want to search on in quotes - "auto park" or "auto park system" for instance. This limits the search to just those words in that sequence. You won't find threads with auto and park which are much too vague and may have caused your error.
On that same search page you can do a few things that really help narrow the search - things like Search Entire Post or Search Titles Only. You can also tell Air Forums which sub-forum to search in and that can be an enormous help if you search on words that will be found in many different forums.
I was able to find much more suitable information related to auto park using the Air Forums search method compared to the site:airforums.com method. The "site" method returns lots of hits but many of them are not related to your question. The Air Forums hits were much more targeted.
Give it another try. When you understand how to use the search criteria it's a very useful too.
