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 "Deflateur du PIB", enclose the phrase in quotes.
Please refer to the following examples:

• Search for Dakar to find all series that contain "Dakar".
• Search for Import OR Export to find all series that contain either "Import" of "Export" indicators or both of them.
• Search for Import AND Graines to find all series that contain both "Import" and "Graines" indicators.
• Search for Import XOR Export to find all series that contain either "Import" or "Export" indicators.
• Search for (Import OR Export) "PIB" to find all series that contain either "Import" or "Export" indicators or the phrase "PIB".
