To use built-in search that has no external dependencies, set the search module to `Pleroma.Activity`:
> config :pleroma, Pleroma.Search, module: Pleroma.Activity
> config :pleroma, Pleroma.Search, module: Pleroma.Search.DatabaseSearch
While it has no external dependencies, it has problems with performance and relevancy.
