@Eloquence pointed out to me that "Cookbook" is not included as a default search namespace on en.wikibooks. At some point we should do an audit of the default search namespaces for the various Wikimedia wikis and tweak them if anything obvious is missing. This will be relatively low impact, but also super straightforward to do since it'll only take around an hour to do the audit and upload a patch tweaking the defaults.
Note to future self: default search namespaces for Wikimedia wikis are stored in wgNamespacesToBeSearchedDefault on line 7094 in operations/mediawiki-config.
