sitecore7.2 - Ordering Sitecore search results -

i have iqueryable<t> object search results object. apply filtering , sorting on search object.

before call getresults(), want order results based on 1 of field's (fieldname - priority) value. items in iqueryable<t> object, want order them desc priority field, items has value field stay @ top , rest @ bottom.

i have fieldmap entry priority field.

search.orderbydescending(i => !string.isnullorempty(i.getitem().getfieldvalue("priority"))) 

the above command doesn't work. apparently, can't use sitecore extension methods iqueryable?

if convert search.tolist(). ordering , convert asqueryable(), following error:

there no method 'getresults' on type 'sitecore.contentsearch.linq.queryableextensions'  matches specified arguments 

is there neat , quick way around this?

cheers

i think need add field searchresultitem , mark int. making assumption field int. make custom class inherits searchresultitem.

public class customsearchresultitem : searchresultitem {     [indexfield("priority")]     public int priority { get; set; } } 

then use in search. order it.

using (var context = contentsearchmanager.getindex("sitecore_master_index").createsearchcontext()) {     var results = context.getqueryable<customsearchresultitem>().where(prod => prod.content.contains("search box text").orderbydescending(t => t.priority); } 

some data found here.
