SharePoint refiners does not work after setting Append Text To Query property of Search Core Result web part

Question

I have created my own search result page with OOB search web part. Everything works as expected.

I have to restrict search with some additional properties so I set "Append Text To Query" property of Search Core Result Web Part and it works perfectly fine.

But when I go to second page of result, refiners shows incorrect count.

for e.g.

total result count is 27

1st Page Refiners shows 27 count

2nd Page Refiners shows 17 count (which is incorrect)

3rd Page Refiners shows 7 count (which is incorrect)

Also refineries are not working if I set fixed query. So if I set fixed query and clicks on any refiners it will always gives the same result coz fixed query overwrite refiners.

Note: I am not using FAST search

Refiner count is not acurate in SharePoint Search before SP2013 - you need deep refinement for this, only available in FAST Search for SharePoint 2010.

Deep Refinement – SharePoint Search only performs a shallow refiner which only allows refinement for the first 50 results in the original query. FAST provides deep refinement which is based on statistical aggregation of managed property values within an entire result set. Because FS4SP provides a deep refiner, the exact count of documents in refiners. http://www.astaticstate.com/2011/01/part-1-fast-for-sharepoint-2010.html
