I had this exact problem the other day.
Partial matches for prefixes or suffixes are currently not supported.

What is indexed there is "home", "gebi", "ayxcvbn", "go", there is no
partial matching for any of those because doing so requires a full table
query (i.e. all entries need to be looked up) which is expensive.

I believe there is work ongoing to resolve this.
