I tried multiple searches, and keep getting the same error message. Both from the quick search bar at the top right of the page, and the "Advanced Search" page. Example, i tried searching for "air filter" and got this result:
The following words in your search query were ignored because they are too common words: filter air.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards.
That seems to be too restrictive to me. But then i tried to search for the word "Jabiru" and it gave me the same result, and again the same with "Onex". A search for "SL30" however, did return some hits (there were only three returns for that search)
Are there customizable settings (for the admin) for the search feature? if there are, than i think they are set to be to restrictive.
