MLTK v2.4 returning max 1000 results and max_memory_usage_mb/max_model_size_mb options cause errors

according to: http://docs.splunk.com/Documentation/MLApp/2.4.0/User/Configurefitandapply and http://docs.splunk.com/Documentation/MLApp/2.4.0/User/Customsearchcommands the **fit** command is supposed to be used like: fit (=)* ()+ (into )? (as )? My SPL is: fit RandomForestClassifier max_memory_usage_mb=10000 max_model_size_mb=500 "targetField" from "dataField1"... and I get this error: Error in 'fit' command: Error while initializing algorithm "RandomForestClassifier": Unexpected parameter: max_model_size_mb The real problem is that I'm getting only 1000 results returned from 5200+ events. I want to get all events back. Can someone help me get all the results? Thanks.
