• The input is case-insensitive. It must contain at least three consecutive letters; e.g. dou in the field "Author(s)" will find all references by Douglass, Doucerin or Dougherty.
• You may also use the asterisk (*) as a wild card, but use it consistently within each searched word; e.g. s*lvicultur* in the field "Title" will find "silviculture", "silvicultures", "sylviculture", "silvicultural", etc., but s*lvicultur (with no final *) will find zero reference.
• Use ellipses to define a range of figures; e.g. 1980...1985 in the field "Year of publication" will find all references published between 1980 and 1985.
• Use the signs < and > to search for figures smaller or larger than a given figure; e.g. <1900 in the field "Year of publication" will find all references published before 1900.
• Use quotation marks to search for a specific chain of characters; e.g. "Becker, B" in the field "author(s)" will find all references by B. Becker.
