Basic search

Enter the term/expression you would like to look for in the Search text box → Click Search

By default the search will be performed according to the "start with" option, which means that you will find records starting with the term/expression you type in the search field. To extend your search to records containing a term/expression (not only "starting with"), we recommend the use, in the search field, of the wildcard character * followed by the term without a space (ex. *meteorology).
