Search Tips

To perform a search on the RCAAP portal home page (designated as simple search) simply enters one or more words (search terms). The default search shows Portuguese and Brazilian resource records. You can choose to search either Portuguese or Brazilian records clicking on the flag of their country.

Be careful to adapt their search for subject. If your search is too broad, select partial aspects and restrict search to certain time periods or to certain type of document. If your searches do not return results, try more general terms, keywords or thesaurus. Also use synonyms and conduct other searches in different languages. Always make sure you are spelling them right!

If you insert multiple words, the system only retrieve documents containing all words inserted in the search box.

If you intend to search for a specific term, use quotation marks. For example: "chemical reactions classification".

Use truncation (*) if you want to harvest root words. For example: if you insert "educ*" the systems retrieves "education", "educating", "educate", "education", etc..

The search engine does not make distinction between upper and lower case, neither consider accents or diacritical marks. So, if you search "Consciência" or "consciencia" the search engine returns the same documents.

To delete a search term use the symbol (-) in front of the search term such as "chemical-reaction". In this case, all documents will be listed with the word "chemical" but do not have the word "reaction".
