//Script to insert AND into keyword searches. Implemented 4/20/2006.
//Original source code is
//copyright Regents of the University of California 2004,
//picked up with modifications from Yale University in 2006 (thanks, Kalee).

//Now extensively modified and condensed by Harish Maringanti at Kansas
//State University, 2006. Specific modifications include adding the ability to
//handle hyphenated terms, e.g.-Levi-Strauss, as well as terms joined by an ampersand.

//Other changes address handling searches that include explicit MARC fields (e.g.- 100A)
//as well as those Voyager index names (e.g.- TKEY), even though we think that less than
//.00005% of humanity knows how to do those searches! While the UCLA/Yale versions address
//this, Harish significantly condensed the code.


//Code below copyright Kansas State University, 2006. We like to share, though, so
//just ask and it's yours.

// Parantheses are addressed: All above should hold good inside parantheses in
// addition to being insensitive to spaces between (,) & any strings.

// var s="One two \"three four\" five six";
