Well, Google has a new trick.
I noticed this week (though I can't confirm exactly when it started) that when you search for a given word, Google returns words with different tone marks from the word you queried. This may be a good thing or a bad thing, depending on what you want to use Google for.
Fortunately, you can get around it by using quotes around your search term. The only exceptions I've noticed to this are non-dictionary words, for which Google still seems to think it knows better than the user.
A few test cases (feel free to replicate these at home):
- I searched กึง (an onomatopoeic word for a loud noise). I was fishing for กึ่ง ('half'). Of the 100 results on the first page, only one contained my actual target. The rest were the much more common word กึ่ง.
- I searched ดิ้น ('wriggle, struggle'), fishing for ดิน ('dirt'). Similar story to above.
- I searched กิ๊ฟ (a non-dictionary word, seen in loans like 'gift shop'). Returns a lot of hits for things like Giffarine (spelled กิฟฟาริน). But this is where it gets weird. Putting quotes around it not only doesn't restrict the search to only my exact query, it actually increased the number of reported hits. I have no idea why.
