Different Results with client.svc and search api

Question

I made a search which is only searching on a specific list. The list has 30132 elements.

• client.svc with the seach Webpart
• _api/search/ with a specfic form

Both searches are returning a different number of totalRows when I search for "*"(client.svc returns 30132 and _api/search returns 29858).

Any idea why and how to solve it?

Thanks in advance

EDIT:

URL for the Ajax request:

https://www.intranet.i/site/_api/search/query?querytext='<searchTerm> AND ListId:<idOfTheList>'&rowlimit=100&trimduplicates=false

Answer 1

It can be the TrimDuplicates functionality!

Try adding &trimduplicates=false to the end of your _api/search string.

This functionality is meant to eliminate "duplicate" results, like documents with exactyl the same names and content.
