If you want to search for complete phrases, enclose them in quotation marks. For instance: "Miguel de Cervantes".
In each field, you can enter one or more words; the operator that links the terms is AND.
The characters * and ? they look for terms that share the same root or words of doubtful spelling. For example: 'ilustr *', it will retrieve the words illustrator, illustrations, illustrated, illustrative, etc.; and 'primiti?e' will recover the terms primitive and primitiue. These characters should not be used as the start of a search term.
