S3VectorClient query filter parameter is complex to use

[MatejNedic]

Describe the feature

When using S3 Vector store current api for filtering requires Document object which makes filtering rather complex.

Writting a filter for example in Python is much easier.

query = s3vectors.query_vectors( vectorBucketName="channy-vector-bucket",
  indexName="channy-vector-index",
  queryVector={"float32":embedding},
  topK=3, 
  filter={"genre":"scifi"},
  returnDistance=True,
  returnMetadata=True
  )

It would be great if Java sdk would support filter(String filterJson) or filter(Map<String, Object>) this would make generic dynamic filtering much simpler.

Complex filter for example with aws cli.

filter '{"$and": [{"category": "tech"}, {"version": {"$gte": "1.0"}}]}'

Writting it with Java is long with a lot of Document.asString() and Document.asMap() or Document mapBuilder

Use Case

S3 Vector Store preview querying and filtering vectors.

Proposed Solution

Allow filter to be plain String which user can serialize on their own or support Map<String,Object>
