I'd search for keyword 'X'. There are some relevant results in the first dozen results, fine. And then I scroll on because I know that there is more, but the search results just... end? Like there's only ever going to be a dozen valid results for any search?
It is a sad day when I have to flip over to bing or somewhere to do a deeper search, rather than staying on-site.
(This is in general a kind of “life hack” — people who speak other languages will often use their own language to title+tag stuff even on otherwise English-language websites; so if you want to find stuff from a specific country, you can often surface higher-relevance content if you put your search keywords in the language that country speaks.)
Other ideograph languages (e.g. Chinese) aren’t so bad when you do this, because enough information is captured per ideograph that losing ordering doesn’t actually change meaning that much. But Japanese is especially bad, because it often “reverts” to the hiragana or katakana alphabets for long strings of words, while still not putting any explicit word-break markers between saidwords. So you end up indexing a “bag of letters.” You can imagine the uselessness of such results.
Or, to put that another way: Japanese-language search “works” on English-language sites when you’re searching a term expressed in kanji. But when the term you want turns out to only have a katakana representation, it’s mostly not going to work.
And yes, Google themselves know all this and have solved all these problems for Google Search long ago. Apparently, the relevant tech never made it into YouTube.
