//  10-08-2002 - Added code to change value of op field in
//               Options frame on submit Search to SimpleSearch,
//               no matter what search operation, simple or advanced,
//               is actually to be submitted.  This is done so that
//               visually user would be able to connect clicking
//               on searchnow in Results frame with the options
//               image.  Also, added same code for browse links in b()
//               which sets op field to corresponding browse operation.
//               For PCR WCW7789.  --Marianna Vinitsky
//  10-17-2002 - Changed archived default to not include archived content.
//               For PCR WCW7898.  --Marianna Vinitsky
//  11-12-2002 - New nescape compatible locking mechanism for search within
//               checkbox.  For PCR WCW8030 and WCW8038.  --Marianna Vinitsky
//  01-04-2003 - Created new function bn (=browse node) to handle author and
//               date views. For PCRs WCW8209 & WCW8279.  --Marianna Vinitsky
//  02-13-2003 - Added support for SEARCH_BY_TOPIC and SEARCH_BY_AUTHOR
//               search operations.  For PCR WCW8368.  --Marianna Vinitsky
//  03-04-2003 - Removed mainWindow variable (was not working in NS 4.75) and
//               replaced function arguments using it with call to 
//               nameForWindow('homepage').  For PCR WCW8127. 
//               --Marianna Vinitsky
//  03-09-2003 - Rewrote b() and bn() to remove frame flicker and resizing.
//               For PCR WCW8597.  --Marianna Vinitsky
//  06-04-2003 - Removed local nameForWindow() function.  It already exists in utility.js.
//                  --R. Pigora
//  07-03-2003 - Modified submitSearch() to return false if the form is submitted.
//               This is part of the fix for PCR#WCW9369.
//                  --R. Pigora
//  07-17-2003 - Renamed JavaScript functions openHelp and openBio to 
//               openSearchHelp and openAuthorBio, repectively, to avoid
//               conflicts with other JavaScript functions of the same name.
//               This fixes PCR #WCW9570 and #WCW9502.
//                  - R. Pigora
//  10-14-2003 - Added support for the Browse By Dataquest Document Clusters.
//               -- R. Pigora
//  12-06-2006 - PCR WCW12881 - Added support for the Browse By Dataquest Quarterly Statistics Clusters.
//                 -- Shrileckha Chaithanya
