How do we compare the field value with a list of values when using the Data Service Search.

Have a look at [Dataservice BoolFilterDesciptor.Should](https://forum.litium.com/t/dataservice-boolfilterdesciptor-should/290)

I have a list of sellers, so I need to compare a field on Person to know if the person is assigned to any of the seller in the list, if I add it as foreach like below, it is not returning any results, is there a way to include a condition like this in search.

foreach (var seller in filterSeller)  
{  
request.Filter(x =\> x.Bool(  
y =\> y.Should(  
z =\> z.Field(PersonFieldNameConstants.AssignedTo, “eq”, seller.Value.ToString()))));  
}

Perhaps something like this:

```auto
   .Should(should => {
      foreach (var seller in filterSeller) 
         should.Field(PersonFieldNameConstants.AssignedTo, “eq”, seller.Value.ToString());
   })));
```
