1 - Search screen, characters and parentheses
Search screen
When searching the SGI-Line Database a search screen with different search entries is used. One or more search terms are entered in one or more of the search entries.
If more than one search term is used in a search entry, the system puts a boolean "AND" between them. The same is valid in between search entries.
Free text - search entry
In the search entry "Free text", it is possible to restrict a search to a specific field in SGI-Line. This is done by adding a two-letter field name beginning and ending with a dot. Example: clay.ct. ct = Keyword (Controlled Term), from the List of keywords or D06.cc. cc = Classification Code, from the Classification system (IGC).
Parentheses
Parentheses are used to nest search terms and override the precedence rules. Example: (clay OR peat) AND settlement.
Wildcards charcters
The wildcard character * matches zero or more continuous characters. The wildcard character can represent characters at the beginning, the middle or the end of a word. Example: *onsolidat*.
Question Mark, ?, is the wildcard character that martches a single character in a search statement. Example: stabili?ation.
Accents
When searching for accents the character is entered without accents. Example: é is searched as e.
Special characters
The character ü is represented and searched as ü. Instead of using these special letters (ü, å, ä ,ö), the wildcard for a single character ? can be used. To type the character ü press the button "¨" and then the "u".
