If you want true full text search capabilities you will need to use a tool designed for that problem like Elastic Search, Typesense or Algolia.

Each of these are standalone services that can be used, but have very seamless integrations when using them as part of Firebase Extensions. Extensions will however need a credit card on file to be enabled.

Note that each of these may have cost implications, and limitations on how to structure your database. Algolia for example requires your text searchable entries to be in one collection.

You might then use a Firestore structure as follows:

foodTypes > meat > recipes > <recipe Id>

where meat and recipes are sub collections.
