I have a field called Location of work (County). It is contains all the county of Hungary and an additional called National (all county). I want to achive that, if the users choose one of a counties, they have to get the result of the selected county and all from the "national". So items which has a value of "national" have to appear in every search results independently which county was selected.
The problem is that this County field is simple select. So it doesn't allow you to choose two or more. But the idea is good. So I set the field at the content type to checkbox and I set a generic search for this field at the search type. So now we can add two or more county for contents so job is almost done, but there is a new problem... :s Now when I want to create a new content, or edit an old one, there is a limit of 15 on the checkbox. Why? I tried with multiple select, but still the same 15 limit.
