+## Properties
+
+### 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.
+
+- **Type**: `SearchEvent`
+
+```vue
+<template>
+  <ol-map ref="map" style="height: 400px">
+    <!-- ... -->
+    <ol-search-control :autocomplete="autocomplete" @select="select"/>
