[vineetaparodkar]

How to retrieve metadata of document using Qdrant and springAI? ?Basically need to show metadata like filename, chunkname etc. Following code snippet describes starting point for retrieving based on query. How to modify this to get metadata of documents too i.e. we need metadata for RAG QnA application which will be pdf names which were provided as context.

Application code - https://github.com/vineetaparodkar/rag-with-openai-spring-ai.git

public String askLlm(String query) {
        List<Document> documentList = vectorStore.similaritySearch(query);

        String systemMessageTemplate = """
                Answer the question in JSON format but do not add ```json``` , based solely on the provided CONTEXT.
                If the answer is not found in the context, respond 'I don't know'.
                CONTEXT:
                     {CONTEXT}
                """;

        Message systemMessage = new SystemPromptTemplate(systemMessageTemplate)
                .createMessage(Map.of("CONTEXT", documentList));
        UserMessage userMessage = new UserMessage(query);
        Prompt prompt = new Prompt(List.of(systemMessage, userMessage));
        OpenAiApi aiApi = new OpenAiApi(apiKey);
        OpenAiChatOptions openAiChatOptions = OpenAiChatOptions.builder()
                .withModel(model)
                .withTemperature(temperature)
                .withMaxTokens(maxToken)
                .build();
        OpenAiChatClient openAiChatClient = new OpenAiChatClient(aiApi, openAiChatOptions);
        ChatResponse response = openAiChatClient.call(prompt);
        String responseContent = response.getResult().getOutput().getContent();
        return responseContent;

    }```
