Subject Re: Index complex JSON data in SOLR
Date Sat, 15 Nov 2014 23:24:10 GMT
Thanks Alex.   I  take a look at the approach of transforming JSON document
before mapping it to the Solr schema at
http://lucidworks.com/blog/indexing-custom-json-data/ .

It's  a walk-around.  But in my case,  if every state has its own price,
 the number of documents needs to be indexed will increase 50 times,  which
may have negative impact on performance,etc.

{prices:[{state:"CA", price:"101.0"}, {state:"NJ",
price:"102.0"},{state:"CO", price:"102.0"}]}

Is there any other better solution?

Thanks,
DL
