+  'Pipeline component for identifying potentially overlapping spans of text'
+api_base_class: /api/pipe
+api_string_name: span_finder
+api_trainable: true
+---
+
+The span finder identifies potentially overlapping, unlabeled spans. It
+identifies tokens that start or end spans and annotates unlabeled spans between
+starts and ends, with optional filters for min and max span length. It is
+intended for use in combination with a component like
+[`SpanCategorizer`](/api/spancategorizer) that may further filter or label the
+spans. Predicted spans will be saved in a [`SpanGroup`](/api/spangroup) on the
+doc under `doc.spans[spans_key]`, where `spans_key` is a component config
+setting.
+
+## Assigned Attributes {id="assigned-attributes"}
+
+Predictions will be saved to `Doc.spans[spans_key]` as a
+[`SpanGroup`](/api/spangroup).
+
+`spans_key` defaults to `"sc"`, but can be passed as a parameter. The
+`span_finder` component will overwrite any existing spans under the spans key
+`doc.spans[spans_key]`.

+## Config and implementation {id="config"}
+
+The default config is defined by the pipeline component factory and describes
+how the component should be configured. You can override its settings via the
+`config` argument on [`nlp.add_pipe`](/api/language#add_pipe) or in your
+[`config.cfg` for training](/usage/training#config). See the
+[model architectures](/api/architectures) documentation for details on the
+architectures and their arguments and hyperparameters.
