# Research: search functionality
How do various mapping platforms offer the 'search'-functionality?
This research in preparation for the search functionality
## Google
The search bar is visible from the start at the top left.
When the search bar is focused, the 'recent'-searches are shown.
When typing a category, options for this category are listed in the sidebar and on the map.
Hovering over them will shop a pin on their location on the map.

Note that filters are suggested on the top left.
When clicking a docter, another side bar (more to the middle) shows the basic info, never obscuring the search results:
![](./Google1.png)
### Mobile
The sidepanels are shown fullscreen, the map view is not visible
## Apple
### Desktop
The newly launched apple Maps has a prominent side bar, showing 'search', 'guides' and 'directions'.
Clicking the search opens another sidebar, which features:
1. The search bar
2. Recently searched
3. Find Nearby (with some common POI categories)
![](./Apple0.png)
Starting to type a search will offer some options under the searchbar; searching results in many options.
This searches nearby (< 100km) and shows a not very obvious pin on the map.
Hovering over an option in the UI has no effect on the map.

Searching a place will open a new sidebar, with some basic information, e.g. the wikipedia article and some pictures
### Mobile
The browser version is not supported on small screens - except on iPhones.
Luckily, there are [plenty online ](https://www.youtube.com/watch?v=m6p3nGzHPUk)[tutorials around](https://www.youtube.com/watch?v=hH1uV1jXY58)
A similar pattern appears here, even though, when selecting an option from the search result list, this option will receive a huge pin.
## Bing
### Desktop
Very similar to google/Apple
![](./Bing0.png)
A popup on the map is shown on hover, but utterly useless as _unhovering_ the entry will hide the popup.
This popup is also triggered when hovering the pin, but here it _is_ possible to move into the popup.
However, clicking the entry or pin will open the entry for the POI:

### Mobile
(Note: trying the responsive design doesn't properly work)
A bottom card shows all the entries, the map view is completely hidden
## OpenStreetMap
A simple list with entries is shown on the left, hovering an entry will reveal the location on the map
![](./OSM0.png)
## Here Maps (Here We Go)
(Note: does not work on librewolf)
This offers a very clean, minimalistic approach with cold colours.
![](./Here0.png)
![](./Here1.png)
![](./Here2.png)
Note that search pins where _two_ entries are at the same location, get a different colour.
## OsmAnd
OsmAnd is not known for it's userfriendliness.
The flow is:
1. Select the search button
2. A screen is opened with a search button on top + tab with recents, categories, ...
3. Typing text will search addresses, placenames and categories
4. Selecting a category will show them as dot on the map
# Other considerations
Support for coordinates (some always interpret lat, lon) and optional reverse geocoding (#1599)
Support for OSM-ids (e.g. node/123, https://osm.org/node/123) (#1671)
Support for layers (categories) and/or switching themes
Switch themes (or layers) via search (https://github.com/pietervdvn/MapComplete/issues/1385)
Open the popup on exact match (https://github.com/pietervdvn/MapComplete/issues/1385)
