Full search for firestore DB -

Is your feature request related to a problem? Please describe.
It isnt possible to do generic matching searches in firestore. You only get >=, =, <= stuff

You need to use third party API like ANGOLA. Se:

Additional context
Most apps allow users to search app content. For example, you may want to search for posts containing a certain word or notes you've written about a specific topic.

Cloud Firestore doesn't support native indexing or search for text fields in documents. Additionally, downloading an entire collection to search for fields client-side isn't practical.
Solution: Algolia

To enable full text search of your Cloud Firestore data, use a third-party search service like Algolia. Consider a note-taking app where each note is a document:

// /notes/${ID}
{
  owner: "{UID}", // Firebase Authentication's User ID of note owner
  text: "This is my first note!"
}

// Initialize Algolia, requires installing Algolia dependencies:
// https://www.algolia.com/doc/api-client/javascript/getting-started/#install
//
// App ID and API Key are stored in functions config variables
const ALGOLIA_ID = functions.config().algolia.app_id;
const ALGOLIA_ADMIN_KEY = functions.config().algolia.api_key;
const ALGOLIA_SEARCH_KEY = functions.config().algolia.search_key;

const ALGOLIA_INDEX_NAME = 'notes';
const client = algoliasearch(ALGOLIA_ID, ALGOLIA_ADMIN_KEY);

------
// Update the search index every time a blog post is written.
exports.onNoteCreated = functions.firestore.document('notes/{noteId}').onCreate((snap, context) => {
  // Get the note document
  const note = snap.data();

  // Add an 'objectID' field which Algolia requires
  note.objectID = context.params.noteId;

  // Write to the algolia index
  const index = client.initIndex(ALGOLIA_INDEX_NAME);
  return index.saveObject(note);
});



------


var client = algoliasearch(ALGOLIA_APP_ID, ALGOLIA_SEARCH_KEY);
var index = client.initIndex('notes');

// Perform an Algolia search:
// https://www.algolia.com/doc/api-reference/api-methods/search/
index
  .search({
    query
  })
  .then(function(responses) {
    // Response from Algolia:
    // https://www.algolia.com/doc/api-reference/api-methods/search/#response-format
    console.log(responses.hits);
  });
