KOSSDA's data search consists of General Keyword search, Detailed Keyword search by index field, and Discover, a browser feature.
For General Keyword searches, it is applied to the Quantitative/Quality Data DB Search, Variable DB Search, and Data related publications DB Search at the same time.
Discover and Detailed Keyword search apply only to the corresponding DB search results tab. If you move to another DB search results tab, the previous search results tab will be initialized..
In order to search effectively, it is recommended to enter a broad search term in General Keyword search and narrow it down using Detailed Keyword search by index field and Discover.
General Keyword search
The search terms you enter are searched in stemmed order and then searched in the order of the most relevance.
Spaces are applied by the OR operator.
If you put a search term in double quotation marks (" "), you'll get an exact match. This is useful when you know the exact data name, series name, institution name, etc., or when you search for phrases of two or more words.
Searching with an asterisk (*) before or after a search term results in a backward or forward match. This does not apply to multiple search terms.
Detailed Keyword search by index field
It searches for data matching the search term (keyword or phrase) for the selected index field. However, double quotation marks ("") and asterisks (*) do not apply.
If you add a refined keyword search, the AND operator is applied to narrow your results.
