declare @Category table (CategoryName  varchar(50)) 

insert into @Category (CategoryName) values('phones')
insert into @Category (CategoryName) values('phone blue')
insert into @Category (CategoryName) values('phone pink')

declare @searchWord varchar(50) = 'phone';
declare @res int;

set @res = (select case when (select count(*) from @Category
                 where substring(CategoryName, 0, CHARINDEX(' ', CategoryName)) = @searchWord) > 0
                 then 1
                 else 0
            end)
if(@res = 1)
begin
    select top 10 CategoryName from @Category where CategoryName like''+@searchWord+'%' and CategoryName like '% %' order by CategoryName
end
else
begin
    select top 10 CategoryName from @Category where CategoryName like''+@searchWord+'%' and CategoryName not like '% %' order by CategoryName
