untill the new Browsing-Page and as well a fix for the search is released, just try to modify your searches. Because we now know, that this issue appears if there is exactly ONE search result, try to use words or phrases, which may offer you more results, even that this means, that your specific search won't be perfect.

If you look for the word "sc1650", you might consider to look for "sc16" instead. This will result in this case for actually 23 results, but your searched content "sc1650" is listed right on the top!
