code:

using System.Linq.Dynamic.Core;

IList<string> filter = new List<string>() { "b", "c" };

var persons = new List<Person>()

    new Person{Name = "zxc", Tags = new List<string>() {"g", "a", "e"}},
    new Person{Name = "qwe", Tags = new List<string>() {"a", "c", "e"}},
    new Person{Name = "cvb", Tags = new List<string>() {"z", "f", "k"}},
    new Person{Name = "fgh", Tags = new List<string>() {"w", "x", "q"}},
}.AsQueryable();

var tags = new Tag[]

I think I got it, can someone confirm it's correct?

var outputExpected = persons.Where(u => filter.Any(r => u.Tags.Any(p => p.Equals(r)))).ToList();
var output = persons.Where("Tags.Any(it in @0)", filter).ToList(); //Correct?

var outputCompactExpected = personsCompact.Where(u => filter.Any(r => u.Tags.Any(p => p.Name.Equals(r)))).ToList();
var outputCompact = personsCompact.Where("Tags.Any(Name in @0)", filter).ToList(); //Correct?
