How to use Entityfieldquery with two field conditions for the same field I need to make a query where the same filed must have one value OR another. Basically:

-&gt;fieldCondition($field_example, 'tid', (array) $var1) ... OR
-&gt;fieldCondition($field_example, 'tid', (array) $var2)


Already saw some examples using TAG but I really don't understand how it's done.
In alternative, can I use dbquery? Or should I avoid it?

Thanks!
You should be able to use db_or(), something like this:

$or = db_or()
  -&gt;fieldCondition($field_example, 'tid', (array) $var1)
  -&gt;fieldCondition($field_example, 'tid', (array) $var2);
$query-&gt;condition($or);
