Showing distance in results
I have Solr 4.2
I need to calculate the distance between a point (0, 0) and lat lng in each
document. I do this
http://<host>:9081/solr/collection1/select?q={!func}dist(2, lat, lng, 0,
0)&wt=xml&indent=true
It works fine but does not show the distance, Please help.

Did you just try just setting up the demo then trying the example? I often
find if I advance step-by-step from the example, it is much easier
to figure things out.
sfield is the name of the field containing the location information,
"store" in the examples
Both "store", and "pt" are required to be defined by the geodist() function.
dist() is a different function query with its own syntax. If you use
geodist(), you must
define pt and sfield.
Best,
Erick

Hi Erick
I tried this link but do not see a straight forward answer.
For example it says:
/You can use the pseudo-field feature to return the distance along with the
stored fields of each document by adding fl=geodist() to the request/
So I tried:
...?q={!func}dist(2, lat, lng, 0, 0)&fl=geodist()&wt=xml&indent=true
<http://> which returnes:
*<lst name="error">
<str name="msg">Error parsing fieldname: geodist - not enough
parameters:[]</str>
<int name="code">400</int>
</lst>*
Also it is not clear what is sfield=store in all examples, like this:
...&q={!func}geodist()&sfield=store&pt=45.15,-93.85&sort=score asc <http://>
So if possible could you explain this either.
