When you setup your search subtabs you have to define a layout for the search prompt screen.  Each subtab can have it's own layout.  As you make those assignments in the HIP Admin tool you'll want to keep this page on hand so you can see (without a long process of trial and error) what each screen is going to look like.

Pay particular attention to my notes.  Some layouts are only appropriate in certain situations and for specific types of search index sets.

 

XSL Template Code Example
(click on a thumbnail to see the full-sized version)		 Notes
ADVANCED Probably should be limited to just keyword indexes since sorting and limiting relate only to keyword indexes.
BROADCAST This layout kind of features multiple search targets.  It has the "Thesaurus" search (which only relates to keyword indexes) so you may want to limit search options to just Keyword indexes.
BROWSE Just like the MULTI-INDEX-DROP.  You have to choose indexes one at a time.
HISTORY This is a unique layout whose sole purpose is to provide "Previous Searches" functionality.  Hint:  in order to have a "Previous Searches" or "Search History" subtab you do have to define a search group, but you won't attach any indexes to this group the way you do a normal group.  The template builds the content dynamically.
MULTI-INDEX Keyword indexes will do a cross-index search.  Browse searches combined will just take the first search term and ignore the list.  a combined keyword and browse search will simply fail.  This layout includes a " Thesaurus" prompt--functionality that only works with keyword indexes.

Recommend you just use this layout for keyword indexes.
MULTI-INDEX-DROP Only allows single-selection, so you won't be able to do crosss-index searching (obviously).
MULTI-INDEX-DROP-TARGETS Remember that your targets on the right hopefully support all or at least most of the indexes you put in your search prompt.
MULTI-INDEX-DROP-TGROUP-LABELS Remember that your targets on the right hopefully support all or at least most of the indexes you put in your search prompt.
MULTI-INDX-DROP-HIDDEN-TARGETS Yeah, the targets are hidden, but it does a consolidated search of ALL your targets.  Waits for all search results to come back before displaying results (and the user doesn't know that it's a catch-all search).  Not a fan of this layout.
POWER As elsewhere, you probably only want to use keyword indexes on this layout.
RESERVE    
SIMPLE No field label.  Meant specifically for the one-prompt "quick" search.
SIMPLE-ADVANCED This layout wil allow the user to do multi-index searches BUT - be aware that HIP only does multi-index searching on keyword indexes (for obvious reasons, if you think about it).

Recommend you ONLY put keyword indexes on this layout.  If you use this for browse indexes and the user enters multiple values, the software only searches the topmost field entered and ignores any other search terms entered farther down the page.

Also...make sure all your targets on the right support the indexes you list on the left.  For example, if all you've done is map your targets on the right to "General Keyword" Common target codes, then your users are going to be confused when they do an author keyword and don't get any results.

SIMPLE-ADVANCED-HIDDEN-TARGETS Read the caveat on SIMPLE-ADVANCED regarding multi-index search layouts.
SIMPLE-ADVANCED-TGROUP-LABELS Read the caveat on SIMPLE-ADVANCED.
SIMPLE-POWER Keyword indexes only!  The proximity and boolean operators are irrelevant to browse and numeric searches.
SIMPLE-POWER-HIDDEN-TARGETS Keyword indexes only.  Even though the search targets are "hidden" it does a complete consolidated search across ALL your targets.  Not sure this is a very good layout to use.  It waits for all the results to come back and doesn't tell you why it's taking so long.
SIMPLE-POWER-TGROUP-LABELS Keyword indexes only.
