The registry plugin allows users to search the Windows registry.
## Special functions (differ from the regular functions)
* Support full base keys and short base keys (e.g. `HKLM` for `HKEY_LOCALE_MACHINE`).
* Show count of subkeys and count of values in the second result line.
* Search for value names and value data inside a registry key (syntax: `[RegistryKey]\\[ValueName]` and `[RegistryKey]\\[ValueData]`)
## The Windows Registry
The registry contains all settings for the Windows operating system and many settings of the installed (Windows only) programs.
*Note: Linux and macOS program ports typical store the settings in it's own configuration files and not in the Windows registry.*
For more information about the Windows registry, see [the official documentation](https://docs.microsoft.com/en-us/windows/win32/sysinfo/registry).

## Important for developers
### General
* The assembly name is cached into `_assemblyName` (to avoid to many calls of `Assembly.GetExecutingAssembly()`)
### Results
* All results override the visible search result via `QueryTextDisplay` to avoid problems with short registry base keys (e.g. `HKLM`).
* The length of a `Title` and `Subtitle` is automatic truncated, when it is to long.
