Mongodb 将mongo连接器限制为特定集合以进行Solr索引

我目前正在尝试使用mongo connector自动向Solr提供数据库更新。通过使用以下命令，它可以正常工作-

mongo-connector -m localhost:27017 -t http://localhost:8983/solr -d mongo_connector/doc_managers/solr_doc_manager.py

然而，它正在为我的mongodb中的每个集合编制索引。我已通过以下方式尝试使用选项-n-

mongo-connector -m localhost:27017 -t http://localhost:8983/solr -n feed_scraper_development.articles -d mongo_connector/doc_managers/solr_doc_manager.py

此操作失败，出现以下错误-

我可以知道，您在哪个文档中找到了-n选项吗？
