Search tips:
- This search form retrieves words of the title, words from the abstract, key words and geographic names
- Use truncation symbol $(dollar sign) to search words with the same root. Example: insect$ retrieves insect, insects, insecta, insecticide, insectenplaag, etc.
- Do not type boolean operators (AND, OR, AND NOT) between words.
- Select the option All words (AND) to link the words (reduce the scope of the retrieval), or the option Any word (OR) to add words (enlarge the scope of the retrieval).
- To search over other fields or to specify the field of the search or to see the index use Basic form or Advanced form.
