_We are using ICU\_Analyzer and ICU\_tokenizer in our application. The search works fine for English words without issue. For Japanese words, Search works fine for Single byte char, and if we pass just one double byte char. But if we pass two double byte char, the search returns no results. Please suggest if any advise._

Thanks for the suggestion. However, we would like to know if there is a way without installing other plugins
