### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon-cpp/issues) and found nothing similar. ### Motivation We want to support hybrid queries that combine scalar predicates, full-text matching predicates, and vector or full-text TopK search through **file indexes**. The existing separate search requests do not provide a unified way to express and execute nested filtering expressions such as: `(price < 10 AND MATCH(body, "apple")) OR (price < 15 AND MATCH(body, "orange"))` These filters should also be usable as the input to a vector or full-text TopK search. Execution should preserve the complete Boolean expression, use available indexes, and fall back to exact scalar evaluation where necessary. The proposal reuses the existing Predicate hierarchy for filtering and keeps TopK as a separate root operation. ### Solution _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
