+### Props from OpenLayers
+
+Properties are passed-trough from `ol-ext` directly.
+Their types and default values can be checked-out [in the official OpenLayers docs](https://viglino.github.io/ol-ext/examples/search/map.control.search.html).
+Only some properties deviate caused by reserved keywords from Vue / HTML.
+This deviating props are described in the section below.
+
+### Deviating Properties
+
+None.
+
+## Events
+
+### select
+
+Emits when selecting an item from the list of search results.
