Query Entity by Regex Google Datastore

Question

I would like to run a query in Google App Engine using Firestore in Datastore mode. What I want to accomplish is to query a string based on a regex. For example, I want a query that would return all entities that match a regex. I could not find anything about regex in the docs. I'm looking for something that would look like the following code.

query := datastore.NewQuery(kind).
    Filter("date =", myRegex)
//then run the query and so forth

Thanks for any help!

Edit: The regex I want to implement looks like the following `"1/\d\d/2020"

Answer 1

Use the following query. A regexp is not needed.

query := datastore.NewQuery(kind).
    Filter("date >=", "1/00/2020").
    Filter("date <=", "1/99/2020").
