Filtering a list based on a value

Based on dropdown value and search text I need to filter a list and return.

Method 1

if (selectedValue == 1 && searchTerm.Length == 0)
return users;

if (selectedValue == 1 && searchTerm.Length > 0)
return users.Where(user=>user.Name == searchTerm).ToList();

if (selectedValue == 2 && searchTerm.Length > 0)
return users.Where(user=>(user.Name == searchTerm && user.Street == "StreetA")).ToList();

if (selectedValue == 2 && searchTerm.Length == 0)
return users.Where(user=>user.Street == "StreetA").ToList();

if (selectedValue == 3 && searchTerm.Length > 0)
return users.Where(user=>(user.Name == searchTerm && user.Street == "StreetB")).ToList();

if (selectedValue == 3 && searchTerm.Length == 0)
return users.Where(user=>user.Street == "StreetB").ToList();

Method 2

if(searchTerm.Length > 0)
{
    if (selectedValue == 1)
    return users.Where(user=>user.Name == searchTerm).ToList();

    if (selectedValue == 2)
    return users.Where(user=>(user.Name == searchTerm && user.Street == "StreetA")).ToList();

    if (selectedValue == 3)
    return users.Where(user=>(user.Name == searchTerm && user.Street == "StreetB")).ToList();
}
else
{
    if (selectedValue == 1)
    return users;

    if (selectedValue == 2)
    return users.Where(user=>user.Street == "StreetA").ToList();

    if (selectedValue == 3)
    return users.Where(user=>user.Street == "StreetB").ToList();
}

I am not convenienced with above logics so please help improve this.

users.Where(user => cond && cond2) is equivalent to users.Where(user => cond).Where(user => cond2)

So you can do the following:

IEnumerable resultStream = users;

if(searchTerm.Length > 0)
    resultStream = resultStream.Where(user.Name == searchTerm);

switch(selectedValue){
    case 1: 
        return resultStream.ToList();
    case 2:
        return resultStream.Where(user=>user.Street == "StreetA").ToList();
    case 3:
        return resultStream.Where(user=>user.Street == "StreetB").ToList();
}
