Search string may contain the logical operators AND, OR and XOR and the operands () and "". AND searches for both words or phrases, while OR and XOR searches for one or the other. If the search string uses AND and OR and XOR 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 "Population Kinshasa", enclose the phrase in quotes.
Please refer to the following examples:

• Search for Population to find all series that contain "Population".
• Search for Homme or Femme to find all series that contain either "Homme" or "Femme" indicators.
• Search for Homme and Qualification to find all series that contain both "Homme" and "Qualification" indicators.
• Search for Homme xor Femme to find all series that contain either "Homme" of "Femme" indicators.
• Search for (Homme or Femme) “Projection de la Population" to find all series that contain either "Homme" or "Femme" indicators or the phrase "Projection de la Population".
