Enter one or more strings to focus the search on a particular type of class or location. Fragmentary strings are typically good enough. The search is NOT case sensitive (upper and lower case are equivalent). Once you have specified the constraints for the search, press the search button! — LB

New discovery (I didn't read my own code carefully!): most of the matching makes use of "Regular Expressions", a universal concept that allows for wildcards and complicated matching effects. For example, if you search class number for "[1-2]...", you'll get all the classes from 1000 through 2999. "." is any character and [1-2] is any number from 1 to 2. -- Lou

The new filter "Any Meeting Info" allows you to enter virtually any fragment associated with class meetings and find classes matching that fragment. Examples include:
   "Mo", "MoWe", "Nau", "02/07/2020", "Web", "Northern Virginia", "Mary", "Rotunda"
I hope you'll find it useful -- LB
