I have an issue
In order to customize the search core results to add sorting, we added code to create our own KeywordQuery Search (based on http://dotnetmafia.com/blogs/dotnettipoftheday/archive/2008/02/19/how-to-use-the-moss-enterprise-search-keywordquery-class.aspx), load the results in the ResponseXmlDoc and out the result.
However the results are inconsistent; here is what we saw.
Search for the word "this"
Scenario 1:
KeywordSearch - Sort by TITLE, Ascending; #results 8
Repeatedly returns the exact same result set
Scenario 2:
KeywordSearch - Sort by ClientName, Ascending; #results 8 - *entirely different set of results than scenario 1*
Repeatedly returns the exact same result set
Scenario 3:
KeywordSearch - Sort by ClientName, Descending; #results 8 - *entirely different set of results than scenario 1 & 2*
Repeatedly returns the exact same result set
Each of these custom queries doesn't seem to like the field "imageurl(image corresponding to the file ex.doc,xls,pdf,ppt)" even though the DefaultSearchCoreResults' xml contains that field.
We are unable to understand the behavior - any ideas would be highly appreciated.
