Complex Sorting List by occurrence of a word by LINQ C# [duplicate]

Answer 1

Maybe you can do it this way? main console program i used to test

static void Main(string[] args)
        {
            var list = SearchResult.GetResult();
            var wordArray = "Geo,JCB".Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
            list.Sort((a, b) => {
                int sum1 = 0, sum2=0;
                foreach (var item in wordArray)
                {
                    sum1 += Regex.Matches(a.Description, item).Count;
                    sum2 += Regex.Matches(b.Description, item).Count;
                }

                if (sum1 < sum2) return 1;
                else if (sum1 > sum2) return -1;
                else return 0;
            });
            foreach (var item in list)
            {
                Console.WriteLine(item.Description);
            }
            Console.ReadKey();
        }

the searchresult class

public class SearchResult
    {
        public string Description { get; set; }
        public static List<SearchResult> GetResult()
        {
            var list = new List<SearchResult>()
            {
                new SearchResult(){Description = "JCB Excavator - ECU P/N: 728/35700"},
                new SearchResult(){Description = "Geo Prism 1995 Geo cart Geo001 -Geo ABS #16213899"},
                new SearchResult(){Description = "Geo Prism 1995 - Geo ABS #16213899"},
                new SearchResult(){Description = "Geo Prism 1995 - ABS #16213899"},
                new SearchResult(){Description = "Wie man BBA reman erreicht"},
                new SearchResult(){Description = "this JCB test JCB"},
                new SearchResult(){Description = "Ersatz Airbags, Gurtstrammer und Auto Körper  Teile"}
            };
            return list;
        }
    }

returning properoutput for what u asked...
which is

Geo Prism 1995 Geo cart Geo001 -Geo ABS #16213899
Geo Prism 1995 - Geo ABS #16213899
this JCB test JCB
Geo Prism 1995 - ABS #16213899
JCB Excavator - ECU P/N: 728/35700
Ersatz Airbags, Gurtstrammer und Auto Körper  Teile
Wie man BBA reman erreicht
