This would indicate that its results are all served up (or stored) in this format, and thus eliminate the issue of pattern matching. I didn't check Yahoo or Lycos or similar engines yet, but it wouldn't surprise me to find out that they were using a similar technique. Thus, a string of characters (or keystrokes) would automatically eliminate any issues with spaces, since I presume they would be automatically discarded in a search if they existed in the query term. Now I wonder how that would work in Thai... I can't test that as my own machine does not have Thai installed, but it would be a simple task for me to find out elsewhere.
I haven't done my site in Thai yet so haven't had to do much testing yet. But strangely enough, while I was doing some checks in OpenFind (Taiwan) just now, I took a closer look at the source and discovered that a search was being sent to the script like this: %bd - where the % serves as an escape character, and bd represents the actual keystrokes.
