# Function: translateRedisFilter()

```ts
function translateRedisFilter(filter?: VectorFilter): string;
```

Defined in: [batteries/vector/redis/index.ts:84](https://github.com/NHTIO/ADK/blob/v1.20260607.0/src/batteries/vector/redis/index.ts#L84)

Compile the neutral filter tree to a RediSearch query fragment. TAG fields hold string /
boolean metadata; NUMERIC fields hold numbers. Returns a fragment to AND with the KNN
clause (or to use alone for a filter-scan). Throws on operators RediSearch can't express.
