Example 1 - Searching in one field with more than one term If you make a search and would like to specify more than one term in a field, e.g. Descriptors, you must: enter the requested terms, separating them with a semicolon. If you do not know whether the term exists in the database, you can use the LIST button (see Example 3). Select the option AND as a term operator if you want to find records where both terms appear in the field; Select the option OR if you want to find the record where at least one of the selected terms appears. Look at the example below:     AND OR NOT   Keywords from Title AND OR  Note that the system will interpret the query as a request for records having in the Descriptor fields at least one of the values Poland OR Germany OR France.
