Range query in Redisearch with Python client

Question

I'm trying to query a range of values in Redisearch with the python client but it's not reading the space in between the values correctly. Any thoughts on how to fix?

conn = redis.Redis(host='localhost', port=6379, db=0)

q = 'FT.SEARCH idx "@date:[20200101 20200301]" LIMIT 0 100'
conn.execute_command(q)

Throws the error:

--------------------------------------------------------------------------
ResponseError                             Traceback (most recent call last)
<ipython-input-31-5321b184194e> in <module>
      2 q = f'''FT.SEARCH idx "@date:[20200101 20200301]" LIMIT 0 1000000'''
      3 
----> 4 res = conn.execute_command(q)
      5 print(res)

Try passing the command separately from the arguments. Here's an example:

conn.execute_command('ft.search', 'books-idx', '@average_rating:[0 1]')

We also have a dedicated Python library for RediSearch built on top of redis-py: https://github.com/RediSearch/redisearch-py
