// Search Expert JavaScript Functions
// File:    searchExpert.js
// Author:  Eric Baars
// WEBCAT:  2.2
// Version: 1.0
// History:
//    20 Jan 2001  Initial creation
//    14 Feb 2001  Sort populated prompt options...ETB
//    26 Feb 2001  Required prompt processing
//    12 Mar 2001  Presort populated options...ETB
//    16 May 2001  New secondary window API...ETB
//     6 Aug 2001  Eliminate populated prompt...ETB
//    28 Aug 2001  Added actionType = "Find" for find button handler.
//                 (Need to know difference bw find and search)...CJF
//     8 Nov 2001  Modified the result of loaded search to be 1/2/3 - KEY_1/2/3...CJF
//    16 Nov 2001  Added feature to call expert search from an expert search...CJF
//    13 Dec 2001  Added flag to submitSearchRequest...CJF
//    01 Feb 2002  Fixed problem with netscape 6.0 and find button...CJF
//    23 Aug 2002  Modified pointer expansion to use POST (for Unicode search)...CJF
//    19 Sep 2002  Modified doSaveSearch to work with new submitSearchRequest function...CJF
//    11 Jul 2005  Added a line of code to set the selecting variable appropriately...WFH

// Majority of JavaScript code moved out of XSL file to speed processing.
