Unexpected characters cause crash

[FallingSnow]

I'm trying to do a prefix text match (for auto complete).

The following queries cause the server to crash with the error below:

• CALL db.idx.fulltext.queryNodes('FERAS', 'ALL%')
• CALL db.idx.fulltext.queryNodes('FERAS', '.*ALL')
• CALL db.idx.fulltext.queryNodes('FERAS', '.*ALL.*')

Error:

redis-server: /home/ayrton/.cache/yay/redis-graph-git/src/redis-graph/src/procedures/proc_fulltext_query.c:58: Proc_FulltextQueryNodeInvoke: Assertion `pdata->iter' failed.
redis.service: Main process exited, code=killed, status=6/ABRT
redis.service: Failed with result 'signal'.

Hi @FallingSnow ,

Thanks for the report! This crash is a bug; a syntax error should be emitted here. We'll resolve this soon!

Our full-text indexes are backed by RediSearch, and should use its syntax. For prefix matching on the literal prefix "ALL", the query would be:
CALL db.idx.fulltext.queryNodes('FERAS', 'ALL*')

Thank you, that syntax works.

CALL db.idx.fulltext.queryNodes('FERAS', 'adoc *') YIELD node AS feras RETURN COUNT(feras) AS count also causes the same crash. I'm sure this is invalid syntax, but this shouldn't cause a crash.

You're definitely right! We'll close this issue once the crash has been replaced with a sensible user-facing error, which I'd expect to be early next week.
