When searching for words in a citation, remember that the names
of publications are usually abbreviated. Example: the Journal
of Geophysical Research is abbreviated J. Geophys. Res. in
citations. A good search would then be: geophys res, with the "both" radio
button selected.
When searching for El Niño or El Niña, do not
attempt to type the n-tilde. The script will automatically find the properly
accented words.
