Search in the right field, e.g. when seeking information with a geographical keyword, do not use the web page reserved for search with a taxonomical keyword.
You may search by a word or part of a word. Be careful not to make a spelling mistake. The more characters you use, the more mistakes you are likely to make. On the other hand, if you type in just a few letters, the search will find a very large number of items. It is recommended to search specific combinations of characters: e.g. typing "ej" will give a more precise answer (fewer items) than "en" (because "en" is found in many words).
Simply type the complete word, be careful not to make any spelling mistakes.
Do not use dots in your abbreviation: e.g. searching for "ULB" is valid, searching for "U.L.B." may not be valid.
Both are available, use either upper or lower case.
Be careful to write the correct accent. It is a misspelling if you forget the accent. In this case the program will have to search by approximation. If you are not sure your word contains an accent, it is better to try the part of the word that does not have an accent.
Be careful to write the official name and not an adaptation of it.
When specified, you may search by more than one word. Use a semi-colon (;) to separate the words. Do not add a space before or after the semi-colon. Be careful not to confuse the "OR" and the "AND" function, see below.
