Hello,

The search results are stored in the HttpContext.Current.Items collection. You should be able to get it as a hashtable using this code:

Hashtable resultRows = RequestStockHelper.GetItem(SearchHelper.RESULTS_KEY) as Hashtable;

However, it is not possible to query this collection using standard SQL query.

So, you could customize the SearchResults control (~\CMSModules\SmartSearch\Controls\SearchResults.ascx.cs). You can access the search results with the aforementioned code in the Search method after the SearchHelper.Search method is executed:

// Search
DataSet results = SearchHelper.Search(searchText, SearchHelper.GetSort(srt), path, DocumentTypes, culture, defaultCulture, CombineWithDefaultCulture, CheckPermissions, SearchInAttachments, Indexes, displayResults, startPosition, numberOfProceeded, (UserInfo)CMSContext.CurrentUser, out numberOfResults, AttachmentsWhere, AttachmentsOrderBy);

// Get search results
Hashtable resultRows = RequestStockHelper.GetItem(SearchHelper.RESULTS_KEY) as Hashtable;

Then, you can bind some custom filter (e.g. drop-down list control) as you need based on resultRows hashtable.

Best regards,
Michal Legen
