### Custom search engines
If you want to add other search contexts to the plugin, you can use the
`$ZSH_WEB_SEARCH_ENGINES` variable. Set it before Oh My Zsh is sourced,
with the following format:
```zsh
ZSH_WEB_SEARCH_ENGINES=(
<context> <URL>
<context> <URL>
)
```
where `<context>` is the name of the search context, and `<URL>` a URL of
the same type as the search contexts above. For example, to add `reddit`,
you'd do:
```zsh
ZSH_WEB_SEARCH_ENGINES=(reddit "https://www.reddit.com/search/?q=")
```
These custom search engines will also be turned to aliases, so you can
both do `web_search reddit <query>` or `reddit <query>`.
