SAB 5.3 MAC Match Word Search not working for Thai language

In Thai language there are no spaces among words. However, while in SAB 5.3 Android the “Match Word” function works (as if the app knew the single words in Thai and knew how to recognize them in the long senteces), in SAB 5.3 MAC it doesn’t. So, as of now, I removed the function “match word” and so the app is able to find that word but together with all the variants (like: if I search for “ants” it will show also “variants”).

I don’t have anything equivalent to test with. I have written a private message to get a copy.

Yes, Ian, thanks! Try to download it from this link:
Can you please tell me how to let the “Search” icon appear on top right? Thanks
