~ wildcard match ('*' will match any number of characters, '?' will match any single character e.g. "PersonForm.Surname ~ '*Smit?'") Note: Surname ~ 'Smith' is the same as Surname = 'Smith'
< LHS is less that RHS. If both sides are numbers, the order is numeric. Otherwise it is alphabetic (applies to all comparison operators)

lc(x) Converts x to lower case, Use for caseless comparisons.
uc(x) Converts x to UPPER CASE. Use for caseless comparisons.
d2n(x) Converts a date (expressed in one of the formats that TWiki can parse) to a number of seconds since 1st Jan 1970. This is the format dates are stored in inside TWiki, and you have to convert a string date using d2n before you can compare it with - for example - the date an attachment was uploaded. Times without a timezone are assumed to be in server local time. If you have date fields in your forms, note that they are not stored in TWiki's internal format, but are stored as text strings. You should still use d2n to convert them to numbers for comparisons, though.
