Example:
/hotplug
This lists all config symbols that contain "hotplug",
- e.g., HOTPLUG, HOTPLUG_CPU, MEMORY_HOTPLUG.
+ e.g., HOTPLUG_CPU, MEMORY_HOTPLUG.
For search help, enter / followed TAB-TAB-TAB (to highlight
<Help>) and Enter. This will tell you that you can also use
/^hotplug
+ When searching, symbols are sorted thus:
+ - exact match first: an exact match is when the search matches
+ the complete symbol name;
+ - alphabetical order: when two symbols do not match exactly,
+ they are sorted in alphabetical order (in the user's current
+ locale).
+ For example: ^ATH.K matches:
+ ATH5K ATH9K ATH5K_AHB ATH5K_DEBUG [...] ATH6KL ATH6KL_DEBUG
+ [...] ATH9K_AHB ATH9K_BTCOEX_SUPPORT ATH9K_COMMON [...]
+ of which only ATH5K and ATH9K match exactly and so are sorted
+ first (and in alphabetical order), then come all other symbols,
+ sorted in alphabetical order.
