According to the HTML Help Workshop online documentation, the HH_DISPLAY_SEARCH API command displays the Search tab in the navigation pane of the HTML Help Viewer. If the HH_FTS_QUERY structure member, fExecute, is "TRUE", a search is performed for the term that is specified in the pszSearchQuery parameter. In reality, the structure members are ignored and the search is not performed.

You can use the HH_DISPLAY_SEARCH command in the following example to display the search tab; however a search is not performed:

HH_FTS_QUERY q ;

q.cbStruct         = sizeof(HH_FTS_QUERY) ;

q.fUniCodeStrings  = FALSE ;

q.pszSearchQuery   = "culture";

q.iProximity       = HH_FTS_DEFAULT_PROXIMITY ;

q.fStemmedSearch   = FALSE :

q.fTitleOnly       = FALSE ;

q.fExecute         = FALSE ;

q.pszWindow        = NULL ;


HtmlHelp(hwnd,"cat.chm",HH_DISPLAY_SEARCH,(DWORD)&q);
