Boost product to TOP of result - randomise

Hi We have the functionality to bring the advertiser products to the TOP of the result, what we have done, added a new property "advertiser" and assign a boost value "10000" using the "..ValueProvider.java" class, I need to bring the product which has the boost value "10000" as the first result in all the sorting criteria, can you please help on the step how to do this.

There is no search matching against the column "advertiser", let me know if you need any more information regarding this

Thanks Selva.
