Answer 1

Depending on your version of mongo-connector, you can either use the -n parameter (pre 2.5.0), or the namespaces configuration setting (2.5.0+):

namespaces Default: Include all namespaces except system and GridFS collections.

NEW in 2.5.0: The namespaces configuration option is used to control how and which MongoDB namespaces are replicated. By default, Mongo Connector will replicate all namespaces except for system and GridFS collections. Namespaces should be given as database_name.collection_name. Each namespace may contain a single wildcard ( ) which matches any characters. For example, db_ .foo matches db_bar.foo and db_a.foo.

You tell mongo-connector which configuration to use with the -c parameter:

mongo-connector -c config.json

To index into a specific collection, give the collection name to the -t parameter :

-t http://localhost:8983/solr/MyCore

To only index specific fields, use the fields configuration option or the -i command line argument.
