Re: Facet values for spacial field

[Erick Erickson]

It seems like the right thing to do here is store something
more intelligible than an encoded lat/lon pair and facet on
that instead. lat/lon, even bare are not all that useful
without some effort anywa...

FWIW,
Erick

AW: Facet values for spacial field

[Köhler Christian]

Hi Eric (and others),

thanx for the the explanation. This helps.

For the usecase: I am cataloging findings of field expeditions. The collectors 
usualy store a single location for the field trip, so the numer of locations is 
limited.

Regards
Chris

You might be able to facet by query, but faceting by
location fields doesn't make a huge amount of sense,
you'll have lots of facets on individual lat/lon points.

What is the use-case you are trying to support here?

Best,
Erick

Re: Facet values for spacial field

[Upayavira]

Note that Solr facets on the *indexed* value, not the stored one. If you
want to facet on the points themselves, store them in your index
alongside as a 'string' field, and facet on that. But as Erick says,
that might give you rather a lot of facets, unless things tend to be
grouped by location.

You might be able to facet by query, but faceting by
location fields doesn't make a huge amount of sense,
you'll have lots of facets on individual lat/lon points.

What is the use-case you are trying to support here?

Facet values for spacial field

[Christian Köhler - ZFMK]

Hi,

I use the new SpatialRecursivePrefixTreeFieldType field to store geo
coordinates (e.g. 14.021666,51.5433353 ). I can retrieve the coordinates
just find so I am sure they are indexed correctly.

However when I try to create facets from this field, solr returns
something which looks like a hash of the coordinates:

Schema:



  
   ...

...
  


Result:
http://localhost/solr/browse?facet=true&facet.field=geo_locality ->
...

 
  660
  290
  214
  179
  165
  143
   ...
 


Filtering by this hashes fails:
http://localhost/solr/browse?&q=&fq=geo_locality:"t4m70cmvej9";
java.lang.IllegalArgumentException: missing parens: t4m70cmvej9

How do I get the results of a single location using faceting?
Any thoughts?

Regards
Chris
