============================================================================

This is a new (and much faster) implementation of veronica -- April 5, 1993.

This search can take either a single keyword, or a string constructed 
of ANDs and ORs and keywords.   Adjacent keywords without an intervening
logical operator are treated as though conjoined by an AND.

An unlimited number of ANDs and ORs may be used in a search expression;
however, parentheses ARE NOT implemented yet.  OR takes precedence over AND.

Search keywords are NOT case-sensitive.  Stemming is not yet implemented.

EXAMPLES:  
    Search on the keyword "chicken".  This will return a directory list of
    all records that have the word chicken in the title field.  Just type-
			chicken

    Search on the keywords "chicken" and "wine".  This returns a directory 
    list of all records that have _BOTH_ "chicken" and "wine".  Type-
			chicken and wine

    Search for the keywords "chicken" or "wine".  This returns a directory
    list of all records that have _EITHER_ chicken or wine. Type-

			chicken or wine

Implementation plans --  we expect to implement both parenthetical 
expressions and stem interpretation in the near future.
