Hi Volker,
I'm happy for you, that you found a solution for your problem. But as Alex 
said... It would be very nice and helpful, if you would publish your 
solution to help other users ;)
cheers

Hey,

is it worthwhile to share the solution you found for other people googling

 I have a question about facets.

 I have documents with a path as part of a document.

 e.g.:

 /america/
 /america/usa
 /america/usa/california
 /america/usa/new-york
 /america/mexico
 /europe/spain
 /europe/germany

 I would like to drill down on an area and get a facet count for the 
 next level.

 If I filter in the facet e.g. for america I would like to get counts 
 for 
  - /america/usa
 - /america/mexico

 I started with using a prefix filter in the facet to filter e.g. for 
 america but then I get 

 - /america/usa
 - /america/usa/california
 - /america/usa/new-york
 - /america/mexico

 but I would like to get the facet counts for only the next level, so I 
 can drill down on the area.

 I tried a search for this topic, but I did not find a solution.

 Hope that somebody can help.

 Kind regards

Re: path facets

[Alexander Reelsen]

Hey,

I remember barely, that was already more than two months ago ;-)

Again with the use case of categories, you may want to drill down in a
hierarchical way, however this does not mean, that your data structures
have to be like that (you could still handle your categories in an array
and apply filters differently, so it looks like a hierarchy). However, I
remember a talk about that at one of the last munich search meetups, dont
see that the presentation is online though (need to reask the speaker for
publishing it)

Re: path facets

[Volker]

do you remember your talk about ecommerce and ES in Hamburg? :-)

viewing and drilling down in a catalogue is also a valid use case, where 
you need to drill down on hirarchical faceted data.

is there an easy way to do that in ES or do I have to aggregate the facets 
by myself?

kind regards

Re: path facets

[Volker]

Hello Alex

thanks for your answer. Actually, it has to be generic, as this was only an 
example. In my use case it is just hirarchical data, where every path is 
from the same type (not country, state, etc).

I am in the process of migrating a lucene + bobobrowse application to ES. 
In bobobrowse there is a PathFacetHandler that does exactly that -- gives 
back facets for the next hirarchical level (and only that). So that it easy 
to drill down into the hirarchical data.

Is there a way to do this in ES?

kind regards

Re: path facets

Hey,

havent spent a lot of thought, if or how you can solve this directly, but
wouldnt it be much easier if you used different fields like 'continent',
'country', 'state', 'city' and would simply aggregate on those and use it
for drill down? Or does it have to be generic and this is just an example?

path facets

[Volker]

dear reader

I have a question about facets.

I have documents with a path as part of a document.

e.g.:

/america/
/america/usa
/america/usa/california
/america/usa/new-york
/america/mexico
/europe/spain
/europe/germany

I would like to drill down on an area and get a facet count for the next 
level.

If I filter in the facet e.g. for america I would like to get counts for 
- /america/usa
- /america/mexico

I started with using a prefix filter in the facet to filter e.g. for 
america but then I get 

- /america/usa
- /america/usa/california
- /america/usa/new-york
- /america/mexico

but I would like to get the facet counts for only the next level, so I can 
drill down on the area.

I tried a search for this topic, but I did not find a solution.

Hope that somebody can help.

Kind regards
