complications guide / info
complications are the little panels that show up on certain searches. some examples are the wikipedia complication, which will show you wikipedia results for searches that result in wikipedia pages; or the unit converter complication, which will attempt to convert units when given a query such as "5 km to miles".
we currently have only implemented the wikipedia and unit converter complications, we plan to add more in the future but for now this is all. furthermore, the unit converter complication only currently supports length units.
an additional note on the unit converter is that it, if given a single unit such as "5km", will attempt to automatically find the simplest alternate unit to represent the value as.
you can disable complications by adding "-complications" to your search query. in the future, this will be a setting in your user settings area.
