Non-Roman Scripts searching needs better support.
Using Chinses scripts as an example, the resource/agent/subject and other lists currently cannot be reorganized according to Chinese scripts.
Also, by using one of the three commonly used Chinese scripts(simplified Han, traditional Han, and Kanji) should be able to search for the equivalent character in the other two.
Finally, languages using Chinese Scripts typically do not have space within a sentence to split words. Therefore, searching engines need to have a list of popular words to do this.
It is also very often that a authority file cannot be searched using the searching box in the collection editing page, but only in the browing page, which I do not understand.
