Provide a description of the help you need

we're encountering a specific challenge regarding the merging of segments retrieved from a query search in our vector database. The issue arises when a query search successfully identifies a matching segment, but the actual content may have been fragmented into multiple segments. Our goal is to seamlessly merge the identified segment with the subsequent three segments to form a cohesive context to feed into a large language model.

for example，a text:

How to be rich?

1. Develop a written financial plan
2. Get into the habit of saving
3. Live below your means
4. Stay out of debt
5. Invest in ways that work for you
6. Start your own business
7. Get professional advice

but the text above was split into two segement. When user query "How to be rich?"，only first half part was found.

Is is it possible to merge the identified segment with the subsequent 1 or 2 segments to form a cohesive context to feed into a large language model?

Hey there, @charliex2! 👋 I'm Dosu, a friendly bot here to help you tackle bugs, answer your questions, and guide you towards becoming a top-notch contributor while we wait for a human maintainer to chime in. Don't hesitate to ask for assistance—I'm here to support you on your journey with Dify!

Based on the context you've provided, it seems you're looking to merge segments of text based on user queries to provide a more complete context for a large language model. This can be achieved programmatically using a combination of natural language processing techniques and logic to determine the relevance and continuity of text segments.

Here's a simplified approach in Python, using pseudo-code to illustrate the concept:

def merge_segments(segments, query):
    """
    Merges an identified text segment with subsequent segments to provide complete context.
    
    :param segments: List of text segments.
    :param query: User query to identify relevant segment.
    :return: Merged text providing complete context.
    """
    # Step 1: Identify the relevant segment based on the user query.
    # This can involve searching for the segment containing the most references to the query.
    relevant_index = find_relevant_segment_index(segments, query)
    
    # Step 2: Determine the range of segments to merge based on context.
    # This example simply merges the identified segment with the next one or two segments.
    # More complex logic can be applied here based on the context or the size of segments.
    start_index = relevant_index
    end_index = min(relevant_index + 2, len(segments) - 1)  # Adjust based on your needs
    
    # Step 3: Merge the segments.
    merged_text = " ".join(segments[start_index:end_index + 1])
    
    return merged_text

def find_relevant_segment_index(segments, query):
    """
    Finds the index of the segment most relevant to the query.
    This function is a placeholder for the actual implementation.
    
    :param segments: List of text segments.
    :param query: User query.
    :return: Index of the relevant segment.
    """
    # Placeholder implementation. Use NLP techniques to find the most relevant segment.
    # For simplicity, this example returns a fixed index.
    return 0  # Replace with actual logic to find the relevant segment based on the query.

# Example usage
segments = ["Segment 1 text.", "Segment 2 text relevant to query.", "Segment 3 text."]
query = "relevant query"
merged_text = merge_segments(segments, query)
print(merged_text)

This code provides a basic framework. The find_relevant_segment_index function needs to be implemented to identify the segment most relevant to the user's query, possibly using techniques such as keyword matching, semantic search, or machine learning models trained for relevance detection. The merging logic in merge_segments can also be adjusted based on the specific requirements, such as the context size needed or the maximum token limit of the language model being used.

As for Dify, it does support text segmentation or splitting functionality. When you upload your business data, Dify helps in completing segmentation and cleaning of the data. This functionality is part of the process to prepare the data for the AI chatbot to use effectively. You can find more details about this in the Dify documentation.

Dify handles the segmentation and cleaning of data during the upload process by automatically segmenting and vectorizing the documents. This process is designed to match users' questions with the most relevant paragraphs or Q&A pairs, depending on the indexing mode selected. Users can choose between "High Quality mode" for higher accuracy using OpenAI's embedding API or "Economic mode" for cost efficiency using offline vector engines and keyword indexing. Additionally, there's a "Segmenting in Question & Answer format" that matches questions directly with similar questions for more precise answers.

The process can indeed be leveraged or modified to merge segments based on a user query. Dify allows for the customization of the segmented and cleaned text by adding, deleting, and editing paragraphs. Users can dynamically adjust segmentation to refine the accuracy of their knowledge base. This is done through the Dify interface by navigating to Document --> paragraph --> Edit to modify paragraph content and custom keywords, or by adding new segments manually or in batches through Document --> paragraph --> Add segment options.

This flexibility in managing document segments and the ability to customize indexing modes provide a robust framework for users to tailor their knowledge bases to specific needs, including the merging of segments based on user queries. You can find more details about this in the Dify documentation.

I hope this helps! If you have any further questions, feel free to ask.
