Biblioscape offers two kinds of searches across all modules. The first one is called Fast Search, which is a full text indexed search. The second one is called Advanced Search, which is SQL-based. For western languages, both searches work. For Chinese, Japanes, and Korean (CJK) records, the Advanced Search works. Fast search only works in a limited way.
Why Fast Search doesn't work for CJK records. Fast Search runs fast because it indexes every word in your database. For western languages, words are separated by a space character. But for CJK text, there is no special character to separate words. The same Chinese character can be a word by itself, but it can also be part of a word. Biblioscape has no easy way to build an index of words. Therefor, Fast Search doesn't work.
Why Fast Search works in a limited way for CJK records. For some data fields like Authors, Keywords, Categories, etc. each word is separated by "; ". Biblioscape will be able to build an index of CJK words based on the "; " as separator. When you type such a word to run Fast Search, Bibliosacpe will find the hits. For example, if the authors field of your record is: xxx; yyy; zzz, Fast Search will work if you type "yyy" or "yy*" to search.
The full text search (Fast Search) engine indexes text using the ANSI driver by default. If you enter German umlauts, the "Fast Search" won't be able to find it. Although other searches like "Advanced Search" work, you may want to make Fast Search work for umlauts as well because Fast Search is used for natural citation matching.
First, please download the utility from http://www.biblioscape.com/download/dbsys.zip. Run DBSYS, go to "Utilities | Restructure...". Go to the folder where you database is stored, select the table "bib". Find the combo box "Language" and change it to the language of your choice. Click the "Save" button to make the changes. You may want to do the same for the table "note".
Once changed, not only the "Fast Search" will work correctly, your references will be sorted correctly as well accordingly to the selected language driver.
