Search panes are defined within SearchList section of the BaseQuery in XXX_CONFIG.XML files, where XXX can be Fred4, Ted4, Shell4, Edadmin4 or Admin4.
For each search pane, there one SearchObjectUI section in the SearchList section within BaseQuery section. Therefore, to locate a search pane, you need to locate first the parent base query.
Locate the parent base query as explained in Finding a base query in the configuration files.
Expand the base query: you will see the groups (optional), directory style list and the search list.
Expand the <SearchList>. You will see one or more search panes.
Expand a searchObjectUI. Details are in SearchList (BaseQuery).
Search panes in browser are defined in <searchObjectUIs> section of xxx_Config.xml files. As those files are loaded as a cascade, look at:
•BasePortalConfig.xml, PortalConfig.xml and gnpc_Config.xml for the standard browser interface
•BasePortalConfig.xml, PortalConfig.xml and gnpcInt_Config.xml for the administrative browser interface
•BasePortalConfig.xml, PortalConfig.xml and gnpcMobile_Config.xml for the mobile browser interface
Other way around to locate the name of the searchObjectUI used in a specific page, edit the search web-part in the Web interface.
Two ways:
1 - Expand the menu "More" on the top right and select "Page manager". In the configuration name's list, select search and then edit.
2 - Modify the search page url in Page.aspx?config=search&editMode=true
Now click the arrow next to Search in the zone 1 and select Edit. The ticked search names are the names of the searchObjectUI you have to look for in the configuration.
