Get by Predicate

GetPred works similarly to Get_key, but instead of querying by a single key, it returns results that match the defined conditions. This allows filtering AI store entries by metadata values.

• store – Name of the AI store to query.

• condition – Predicate condition that defines which entries to return. This can include equality, range, or custom predicate logic.

The result contains a list of entries matching the predicate.

• The predicate condition can be extended to other metadata fields beyond "brand".

• This request is specifically designed for AI store queries.
