SearchFilter incorrectly split value with istartswith filter

[Arti3DPlayer]

When we define filter field with istartswith as described in docs

search_fields=["^address", ]

and will try to search by string that contains spaces: 123 Main St, it will not work, because split term in this case is working incorrectly and split string as:
Q(address_istartwith="123) | Q(address_istartwith="Main") | Q(address_istartwith="St") (source)

Expected behaviour to generate query like:
Q(address_istartwith="123 Main St")

So... I don't think it's necessarily(?) that obvious which behaviour I'd expect, and might depend on the UI.

As for me this behaviour does not make sense for any real example. For example: in my project I have autocomplete widget for different entities like User names Company Names Addresses , where I have ^name and this is odd when user start typing: 123 hit space and result disappear

Yeah. I'd probs override 'filter_queryset' and move on with your day.
