How to search multi keywork in linq query - entity-framework

Question

i have this code in homepage
CheckBox[] ch= new CheckBox[12];
ch[0] = ChkContextA;
ch[1]= ChkContextB;
ch[2]= ChkContextC;
ch[3]= ChkContextD;
ch[4]= ChkContextE;
ch[5]= ChkContextF;
ch[6]= ChkContextG;
ch[7]= ChkContextH;
ch[8]= ChkContextI;
ch[9]= ChkContextJ;
ch[10]= ChkContextK;
ch[11]= ChiContextL;
for (int i = 0; i < 11; i++)
if (ch[i].Checked) search += ch[i].Text + " ";
Response.Redirect("SearchEstate.aspx?content="+search);
and this code in SearchEstate
var content = Request.QueryString["content"];
RealEstateEntities db = new RealEstateEntities();
var query = from O in db.Owners
join E in db.Estates on O.OwnerID equals E.OwnerID
join P in db.Properties on E.PropertyID equals P.PropertyID
where P.Facilities.Contains(content)
select new
{
regdate = E.RegisterDate,
region = E.Region,
Estype = E.EstateType,
Fac = P.Facilities,
deal = P.DealType,
price = P.TotalCost,
img = E.Picture,
addrss = O.Address,
area = P.Area,
tel = P.TellNum,
bed = P.RoomNum,
park = P.ParikingNum
};
Repeater2.DataSource = query.OrderByDescending(x => x.regdate);
Repeater2.DataBind();
when user checked some checkbox "content" for example have this value:
SearchEstate.aspx?content=ContextB ContextE ContextJ
I Want search this values in Facility field in db
How can I do this? (Sorry for my bad English)

Answer 1

I have the feeling your are looking for something along the lines of this query:
var content = Request.QueryString["content"];
string[] contentArray = content.Split(' ');
//...
var query = //...
where P.Facilities.Any(f => contentArray.Contains(f.FacilityName))
//...
(or instead of FacilityName some other property of Facility)
But I am not sure.
