 QuickSearch provides fast, full text, multi-keyword searching
 using "AND", "OR", and "NOT" boolean search operators.

 Up to 10 keywords may be searched at one time. Keywords and
 operators must be separated by one or more spaces and keywords
 must begin with an alphanumeric character.

 Case is not significant. Plural and singular terms are treated
 equivalently. When no operator is specified, "AND" is assumed.
 (eg. "The hills are alive" = "The AND hills AND are AND alive")

 Keywords are parsed from left to right. For multi-keyword
 searches, enter all "OR" operations first, followed by "AND"
 and "NOT" operations in any order.

 To retrieve files, enter file numbers separated by one or more
 spaces. To specify a range of numbers, enter /N,N or /N-N.
 After searching, range selections are limited to the last 100
 displayed file numbers. There is no limit when Listing files.

 If your keyboard does not have an ESC key, use CTRL-[ instead.
