The intrinsic search engine of JKS web sites uses advanced site search technology to fully index the current collection of pages and documents exceeding 2,200.

Certain keywords could generate tens of "document found" hits, as results are ranked by hierarchy. The number of outputs can be reduced by either modifying the keyword(s) or by using the Advance Search page.

The JKS web contains sites with very few exceptions written in English.

Keywords should be entered into the search box by using Latin alphabet only. Both British and American spelling are acceptable. Note to users of double-byte codes: romaji, etc. could be used only in half-width.
