# Searching by Location
Performing a radial search using our Events API's `within` parameter is a common way to find events that impact your locations of interest. See our guide on [radial searches](https://docs.predicthq.com/getting-started/guides/geolocation-guides/searching-by-location/find-events-by-latitude-longitude-and-radius) and the within search parameter.
Which events are returned by a radial search depends on their location and geometry type. The image below shows the result of the example radial search performed in our [WebApp](https://control.predicthq.com/search/events/map?category=public-holidays,observances,politics,conferences,expos,concerts,festivals,performing-arts,sports,community,daylight-savings,airport-delays,severe-weather,disasters,terror,academic\&place.scope=6252001\&active.gte=2020-08-06\&active.lte=2020-09-05\&state=active\&within=4mi%4040.6441,-73.9393): A 4-mile radius around a point in Brooklyn, New York, USA - the search area is the blue circle.
| LOCATION AND GEOMETRY TYPE | RADIAL SEARCH MATCHING CRITERION |
| ------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Point event with Point geometry | Returned if their point falls within the specified radius. In the image below, matching point events are the dots within the blue circle. |
| Area event with Polygon or MultiPolygon geometry | Returned if any part of the polygons intersect with the specified radius. In the image below, matching events with polygons intersect with the blue circle. |
| Area event with Point geometry | Returned if the radial search location (the provided lat,lon coordinates regardless of radius) is a child place of the area event's place. In the image below, the dot outside the blue circle is an area event without a polygon. This event covers all of New York City, and since the radial search's location is in Brooklyn, a child place of New York City, this area event was returned also. |
We recommend that if you are looking for events around a location like a store, hotel, or other bricks and mortar location, you use a radial search (a `within` query) to find events that impact you.
In order to set your radius we recommend using the [Suggested Radius API](https://app.gitbook.com/s/kEFs8urDbSJqBmXUI3Lv/suggested-radius/get-suggested-radius). Call the Suggested Radius API and supply the latitude and longitude of the location and use that radius to look for events around a location. The Suggested Radius API is powered by a machine learning model that looks at factors like population density, the events around a location, the customer’s industry, and many other factors to determine the ideal radius.
You can also search for events occurring, in particular, Geonames Places using the `place.scope` parameter with Place ids. In our [Severe-Weather Events Data Engineering notebook](https://docs.predicthq.com/getting-started/guides/events-api-guides/severe-weather-events-data-science-guides), we provide code examples to find Place ids for your locations of interest.
