El Corpus del Español: This 100 million word corpus of Spanish texts has been funded by the NEH and has been created by Prof. Mark Davies of Brigham Young University. In addition to being very fast, the search engine allows a wider range of searches than almost any other large corpus in existence.
Real Academia Española: This site includes a modern dictionary, as well as a search capability that includes all editions of the Academy's dictionary, since 1726. This site also includes the searchable Corpus de Referencia del Español Actual (CREA) and Corpus Diacrónico del Español (CORDE), which can be found under "Consulta banco de datos".
O Corpus do Português: Also operated by Prof. Mark Davies, along with Prof. Michael J. Ferreira, this website allows you to quickly and easily search more than 45 million words in more than 50,000 Portuguese texts from the 1300s to the 1900s. The interface allows you to search for exact words or phrases, wildcards, lemmas, part of speech, or any combinations of these. You can also search for surrounding words (collocates) within a ten-word window (e.g. all nouns somewhere near cadeia, all adjectives near mulher, or all nouns near girar).
