# `mix phoenix_kit_knowledge_base.rescan`
[🔗](https://github.com/BeamLabEU/phoenix_kit_knowledge_base/blob/v0.1.0/lib/mix/tasks/phoenix_kit_knowledge_base.rescan.ex#L1)

Reconciles vault indexes with the markdown files on disk.

The web UI has a Rescan button; this is the same operation from a shell, so it
can run from cron, from a deploy script, or from a git hook after a `pull`.

    # every vault
    mix phoenix_kit_knowledge_base.rescan

    # one vault, by slug
    mix phoenix_kit_knowledge_base.rescan research

    # quiet: only print vaults that actually changed, and errors
    mix phoenix_kit_knowledge_base.rescan --quiet

Exits non-zero if any vault reported an error, so a cron job or CI step fails
loudly rather than logging into the void.

This is a separate OS process from the running app, with no PubSub: browsers
open on a vault pick its changes up on their next navigation, not at once.
To refresh them immediately, call `PhoenixKitKnowledgeBase.Rescan.run/1` on
the live node instead (a release's `bin/<app> rpc`).
