== Inputs
When a watch is triggered, its _input_ loads data into the execution
context. This payload is accessible during the subsequent watch execution
phases. For example, you can base a watch's condition on the data loaded by its
input.
{watcher} supports four input types:
* <<input-simple,`simple`>>: load static data into the execution context.
* <<input-search,`search`>>: load the results of a search into the execution
context.
* <<input-http,`http`>>: load the results of an HTTP request into the execution
context.
* <<input-chain,`chain`>>: use a series of inputs to load data into the
execution context.
NOTE: If you don't define an input for a watch, an empty payload is loaded
into the execution context.
