    Hi Prasad,

    Please try with the below LINQ.
    Assume you have all records in MedicalList List.

    <code>
    List<string> selectedList= MedicalList.Select(records => (recordname.contains("pain") ||
    recordname.contains("abdominal") ||
    recordname.contains("diabetes ")).ToList();
    </code>

    Here selectedList will display the records what you expected.

    Please try and let me know.

    You can use "Contains" for compare the string inside of the collection. You can select the using "Any". Followings is the sample Linq

    public bool ContainsAny(string SearchText, IEnumerable<string> searchTerms)
    {
    return searchItems.Any(searchItem => SearchText.ToLower().Contains(searchItem .ToLower()));
    }

    You have another obtion also for "FindAll" and "ContainsAny". Following is the sample code

    List<string> foundUsers = allUsers.FindAll(s => s.ContainsAny(searchString));
