Thanks for your prompt reply. But it still doesn't work. My problem is that I need to search by 2 or more values in the same field. Here is my query: http://www.unesco.org/...national_legislation
I have a field "information type". In this field I have different values (scrolling list), among which "national policy" and "national legislation". I only manage to search by one value. Perhaps what I want to do is not possible. But it would be good to know.
If you could help with this it would be really nice.
