Describe the bug:
According to documentation, filtering with syntax @country:{USA|GBR|CAN} should work for hybrid queries, but it does not.

Expected:
This is expected to work as an equivalent for an OR filter, e.g. (@country:{USA} | @country:{GBR} | @country:{CAN}).

Actual:
The query does not return results or is not accepted, while the equivalent OR filter in parentheses works as expected.

Example:
This works (returns results):

FT.SEARCH idx_hnsw_cosine '(@country:{USA} | @country:{GBR} | @country:{CAN})=>[KNN 5 @text_embedding_vector $query_vector]' PARAMS 2 query_vector $'...'

This does not work (no results or error):

FT.SEARCH vector_index_x '@country:{USA|GBR|CAN}=>[KNN 5 @text_embedding_vector $query_vector]' PARAMS 2 query_vector $'...'
