Full-text search errors for prefix match

[okimonhgb]

Describe the bug
Fulltext search gives error if I want to search for words that match a given prefix:
FT.SEARCH idxe:content "@text:football*"
"ERR Query syntax error"

To Reproduce
Steps to reproduce the behavior:

1. Insert records : A json type key with a text field called "text".
2. Create a full-text index: FT.CREATE indxe:content ON JSON PREFIX 1 contents: SCHEMA
   $.text AS text TEXT
3. Query records using : FT.SEARCH idxe:content "@text:football*"
4. It gives error: "ERR Query syntax error"

Expected behavior
for exact search I get no error:
FT.SEARCH idxe:content "@text:football"
My existing app. running on Redis doesn't get any error for prefix matching as expected:

https://redis.io/docs/latest/develop/interact/search-and-query/query/full-text/

...
Word prefix
You can also search for words that match a given prefix.

FT.SEARCH index "prefix*"

@dranikpg can you kindly take a look? 🙏

@okimonhgb is it full text search? it's not supported. indeed I do not see that it is clearly specified in the documentation.

[okimonhgb]

@romange yes it is full text search. It works for exact word searches but seems doesn't support word prefixes.
Is it planned to be supported in near future? Is there any workaround? We want to use replace our redis instance with dragonfly but this problem breaks existing codes.

[romange]

Unfortunately it won't be implemented in near future.

[okimonhgb]

Ok. I understand there is also no workaround?
So we should plan according to this.
Can I keep this issue open?
Best regards,

[romange]

Sure :)
