Help on indexing nested documenta in MongoDB

[Wendy2 <we...@rcsb.org>]

Hi fellow Solr users,

I am looking for a way to index nested documents in mongodb using Solr's
DataImportHandler. Is there any recommendations? 

I googled on the web in the last two weeks and found the following posts. I
was able to index the top level fields W/O any issue, but had trouble in
indexing the nested object. 

In the past, I used mongo-connector to index simple JSON documents in
mongodb. But for deeply nested documents in MongoDB, I am looking for a more
powerful way to do it. 

Is there any recommendations or good posts on indexing nested documents in
mongodb using Solr's DataImportHandler?   Thanks!
