  === Removing a single document
  
  To remove a single document you use `link:../../apidocs/io/vertx/ext/mongo/MongoClient.html#removeOne-java.lang.String-io.vertx.core.json.JsonObject-io.vertx.core.Handler-[removeOne]`.
  
  This works just like `link:../../apidocs/io/vertx/ext/mongo/MongoClient.html#remove-java.lang.String-io.vertx.core.json.JsonObject-io.vertx.core.Handler-[remove]` but it removes just the first matching document.

negative.code: 
  === Removing documents
  
  To remove documents use `link:../../apidocs/io/vertx/ext/mongo/MongoClient.html#remove-java.lang.String-io.vertx.core.json.JsonObject-io.vertx.core.Handler-[removeDocuments]`.
  
  The `query` parameter is used to match the documents in the collection to determine which ones to remove.
