I am using Collapse to get first element of group by with the search api. but it is working if my Limit+offset is less than 10000. for more than 10000 i am using the scroll api , collpase is not working with scroll , what laternative i can use here . My code Snippet is

return await \_elasticClient.SearchAsync(bd =\> (((input.Limit +input.Offset) \> 0 && (input.Limit + input.Offset) \< 10000)  
? bd.From(offset).Size(limit).Collapse(x =\> x.Field(f =\> f.SnippetId))  
: bd.Scroll(TimeSpan.FromMinutes(30)).Take(limit))  
.Query(TDMSnippetTableSearchQuery(input, includeCompetitors)  
));

Please help me to resolve this.
