[MarkLogic Dev General] using lib-search:search-summary

[Alan Darnell]

I think I found the answer to my problem with facet counts not  
decreasing as new search:values elements are added to a search- 
criteria element.  In the function "transform-value-facet-query" in  
lib-search.xqy, has this code:

let $new-values := (
	if ($scope instance of element(search:element-attr)) then
                ...
             else                $search-criteria/search:values
[fn:not(
                     (./search:element/search:local-name)[1] = $scope/ 
search:local-name and
                     ((./search:element/search:namespace)[1] = $scope/ 
search:namespace or
                     (fn:empty(./search:element/search:namespace/ 
text()) and fn:empty($scope/search:namespace/text())))) ]
             ,
                 if ($new-value) then
                         <values>
                                 {$scope}
                                 <value>{$new-value}</value>
                         </values>
                 else ()
                 )
         return
         <search:search-criteria>
                 {$search-criteria/@*}
                 {$search-criteria/*[fn:local-name(.) ne "values"]}
                 {$new-values}
         </search:search-criteria>
}

By commenting out the logical test following the line $search-criteria/ 
search:values, the facet counts adjust as new values are added to the  
search criteria.
