​
Chunk Length Configuration

​
INDEXING_MAX_SEGMENTATION_TOKENS_LENGTH

Configuration for document chunk length. It is used to control the size of text segments when processing long documents. Default: 500. Maximum: 4000.

Larger Chunks

  • Retain more context within each chunk, ideal for tasks requiring a broader understanding of the text.
  • Reduce the total number of chunks, lowering processing time and storage overhead.

Smaller Chunks

  • Provide finer granularity, improving accuracy for tasks like extraction or summarization.
  • Reduce the risk of exceeding model token limits, making it safer for models with stricter constraints.

Configuration Recommendations

  • Choose larger chunks for context-heavy tasks like sentiment analysis or document summarization.
  • Choose smaller chunks for fine-grained tasks such as keyword extraction or paragraph-level processing.
