Windows Desktop Search not returning QueryFocusedSummary

Question

When searching through files indexed using Windows Desktop Search, it would be nice if I could see a snippet of the text within the document that is related to the search t

Answer 1

A colleague of mine ran into this problem recently. QueryFocusedSummary and QueryFocusedSummaryWithFallback are indeed not accessible via OLEDB. They are, however, accessible via Shell.

In the Windows SDK, there is a sample, $WIN_SDK/Samples/winui/shell/appplatform/ExplorerBrowserSearch, which will get you set up on using Shell functions to perform a search. From here, it should be trivial to add support for QueryFocusedSummary and QueryFocusedSummaryWithFallback via the Shell Property Keys PKEY_Search_QueryFocusedSummary and PKEY_Search_QueryFocusedSummaryWithFallback respectively.

Answer 2

Since you didn't post any code I have to speculate a bit...

I assume you are using OleDB/SQL to execute a query...

Neither QueryFocusedSummary nor QueryFocusedSummaryWithFallback are real columns and thus NOT available via OleDB/SQL !

The only columns available this way are AFAIK

AutoSummary 
Contents 
EntryID 
GatherTime 
Rank 
Store 

QueryFocusedSummary and QueryFocusedSummaryWithFallback are IIRC properties accessiable via COM or a Shell interface .
