[root@mongdb ~]# mongorestore --help
Usage:
mongorestore <options> <connection-string> <directory or file to restore>
Restore backups generated with mongodump to a running server.
Specify a database with -d to restore a single database from the target directory,
or use -d and -c to restore a single collection from a single .bson file.
Connection strings must begin with mongodb:// or mongodb+srv://.
See http://docs.mongodb.com/database-tools/mongorestore/ for more information.

--noIndexRestore don't restore indexes
--convertLegacyIndexes Removes invalid index options and rewrites legacy option values (e.g. true becomes 1).
--noOptionsRestore don't restore collection options
--keepIndexVersion don't update index version
--maintainInsertionOrder restore the documents in the order of their appearance in the input source. By default the insertions will be performed in an arbitrary order. Setting this flag also enables the behavior of --stopOnError and
restricts NumInsertionWorkersPerCollection to 1.
-j, --numParallelCollections= number of collections to restore in parallel
--numInsertionWorkersPerCollection= number of insert operations to run concurrently per collection
--stopOnError halt after encountering any error during insertion. By default, mongorestore will attempt to continue through document validation and DuplicateKey errors, but with this option enabled, the tool will stop
instead. A small number of documents may be inserted after encountering an error even with this option enabled; use --maintainInsertionOrder to halt immediately after an error
--bypassDocumentValidation bypass document validation
--preserveUUID preserve original collection UUIDs (off by default, requires drop)
--fixDottedHashIndex when enabled, all the hashed indexes on dotted fields will be created as single field ascending indexes on the destination最终，进入到导入后的库查看数据
