== model
The `model` function retrieves and caches logistic regression text classification models that are stored in a SolrCloud collection. The `model` function is designed to work with models that are created by the <<train,train function>>, but can also be used to retrieve text classification models trained outside of Solr, as long as they conform to the specified format. After the model is retrieved it can be used by the <<stream-decorators.adoc#classify,classify function>> to classify documents.

+* `format`: (Optional) Date template to format the date field in the output tuples. Formatting is performed by Java's SimpleDateFormat class.
