[Koha] Mapping MARC21 to Advanced Search

Hi Rubén!

In the manual, there is a kind of mapping section for searches that 
gives you the indexes for each marc field: 

If you want to know what index is used for each search limit, you can 
make a search in Koha and look in the breadcrumbs for "Search for 
'...'". This will give you the index used for the search. For example, 
if I search with Danish in the language limit, it returns 'ln,rtrn:dan'. 
According to the manual, the 'ln' index is mapped to 008, position 
35-37, and 041.

I hope this helps.

Maybe it could be more explicit in the manual. I will look into that!
