TL;DR: Add the core plugins search functionality to the API, or document it better, as I cannot find it.
This may simply be an skill issue, but I cannot figure out if it is possible to access the core plugins search capabilities via the obsidian-api. I only see prepareFuzzySearch(query: string) and prepareSimpleSearch(query: string) and I am unable to get simple search to search for groups of words. The repository does not allow for Issues or Discussions so I am writing here.
