Subject Re: Python Response Bug?
Date Thu, 25 Jun 2009 15:10:30 GMT
The first JSON is invalid as you see because of the missing value.

:, is not valid JSON syntax.

The reason it works for string type is because the empty string '' is a
valid field value but _nothing_ (the first examepl) is not. There is no
empty float placeholder that JSON likes. So either it has to be an empty
string or some legitimate float value.

FAIK, Solr doesn't generate empty numeric values compatible with JSON.
zero and null are different things.
