Search string may contain the logical operators AND,OR and XOR and the operands () and "".
AND searches for both words or phrases, while OR searches for one or the other.
If the search string uses AND and OR at the same time, the AND operation takes priority,
unless you enclose the OR operation in parentheses, as in (A or B) and C. To find
an exact phrase, such as "Formation", enclose the phrase in quotes.
Please refer to the following examples:
- Search for
Population to find all series that contain "Formation".
-
Search for Oman OR Kuwait to find all series that contain either "Oman" or "Kuwait" indicators.
-
Search for Goods AND Services to find all series that contain both "Goods" and "Services" indicators.
-
Search for Goods XOR Services to find all series that contain either "Goods" of "Services" indicators.
-
Search for (Product OR Formation) "Qatar" to find all series that contain either "Product" or "Formation" indicators or the phrase "Qatar".
