Hi,

I'm setting up the mapping for an index and I have a field containing long German texts.  
I would like to use the Compound Filter to divide the words, so that I could find results also for the "sub-words".

The question is:

- where I can find a good dictionary to use for German?
- (but mainly) what should be the format of this file? A specific extension? One word per line? A comma-separated-values list without line breaks?  
I found a dictionary but has a format like this:

Äbte/N  
Äbtissin/F  
Ächtens  
Ächtung/P  
Äcker/N  
Äderchen/S  
Äffin/F  
Ägide  
Ägypten/S  
Ägypter/FNS

And I don't really understand the meaning of the suffix after the slash; and I wonder if Elasticsearch will instead.  
Where can I read more specification about how the dictionary needs to be?
