The searches are fairly self-evident. You may search for one or two keywords. In the latter case, you may have the logical functions AND, OR or AND+NOT between the two.
For special letters or combinations of letters, use the
symbols '?' (one free character) or '*' (free string).
Examples using the AUTHOR field:
M?ller (59 hits) (Muller, Müller, Miller, Möller, Møller,.. but not Mueller)
M*ller (93 hits) (those above, plus Mueller)
M*ller AND NOT Miller (73 hits, best alternative).
You may search for isolated words but not for strings. To look for Y-F Zhao, eliminating other Zhao:s, use AUTHOR Zhao AND AUTHOR Y-F (12 hits).
A search for ANY gold will give papers on gold or its compounds and papers in Gold Bulletin (116 hits). A search for TITLE gold* finds 118 hits on gold or its compounds.
An efficient way to search for data on a given element, such as gold, is to combine a case-specific (so far two-letter) chemical symbol and a name: [case specific] TITLE Au OR TITLE gold.
