AI Search - AI Search keyword search supports Japanese, Chinese, and Korean queries

AI Search keyword search with the trigram tokenizer now matches Japanese, Chinese, and Korean queries, including full natural-language questions such as 経費精算の締め日はいつですか？. Previously, a query without spaces was treated as a single exact phrase and usually returned no keyword results.

The porter tokenizer does not work well for these languages. If your content is in Japanese, Chinese, or Korean, set keyword_tokenizer to trigram. Changing the tokenizer triggers a full reindex.
