Configure metadataFieldsToFilter of MongoDBVectorStoreConfig in properties file

[ilopezluna]

It would be great to make metadataFieldsToFilter of MongoDBVectorStoreConfig configurable from properties

Expected Behavior

To define in application.yaml

vectorstore:
    mongodb:
      metadata-fields-to-filter:
        - fieldA
        - fieldB

Current Behavior

You have to define it programmatically:

@Bean
    public MongoDBAtlasVectorStore vectorStore(MongoTemplate mongoTemplate, EmbeddingModel embeddingModel) {
        MongoDBVectorStoreConfig config = MongoDBVectorStoreConfig.builder()
            .withCollectionName("custom_vector_store")
            .withVectorIndexName("custom_vector_index")
            .withPathName("custom_embedding_path")
            .withMetadataFieldsToFilter(List.of("author", "year"))
            .build();

        return new MongoDBAtlasVectorStore(mongoTemplate, embeddingModel, config, true);
    }
