4. Phrase Matching in Marginalia Search (www.marginalia.nu | Archive)
63 points by marginalia_nu | 2024-09-30 11:42:55 | 7 comments

Dehyped title: A custom compression scheme for document IDs significantly reduces index size by exploiting their unique statistical distribution.

Summary:

  • The author was working on compressing a search index that initially took up 175 GB of space.

  • Removing metadata and indexing structures reduced the size to 85 GB, demonstrating the potential for compression.

  • Document IDs in the index were constructed with specific bit ranges: bits 0-26 for document ordinal, bits 26-56 for domain ID, and bits 56-63 for a ranking component. This design aimed to enable intelligent ID reuse while keeping them within 64 bits.

  • The difference between consecutive document IDs exhibited three distinct modes due to the construction scheme:

    • Small changes in bits 0-26 (most common).
    • Small changes in bits 56-63 and unpredictable changes in bits 0-56.
    • Small changes in bits 25-56 and unpredictable changes in bits 0-26.
  • A custom compression scheme was developed to address these modes:

    • Code 0: Increment the document ordinal using Elias gamma coding (efficient for small values).

    • Code 1: Update both ordinal and domain ID using Elias delta coding (favors slightly larger values than gamma).

    • Code 2: Update rank, set domain ID to a new value, and set ordinal ID to a new value. All values are encoded using Elias gamma and uncompressed representations.

    • Code 3: Directly read an uncompressed document ID for bootstrapping the initial list.

  • Elias delta coding is similar to Elias gamma coding but uses gamma coding to represent the number of significant bits in the input value, making it suitable for slightly larger values.

  • This custom compression scheme achieved a remarkable reduction in size, bringing the index down to just 10 GB.

  • This outperformed general-purpose compression algorithms like zstd (25 GB), highlighting the advantage of tailored solutions for data with specific characteristics.

Comments:

  • Praise for the Feature: Users express admiration for the new phrase matching feature, highlighting its effectiveness in delivering relevant search results. They cite examples like searches for "bicycle touring in France" yielding accurate and well-formatted results.

  • Technical Curiosity: Users inquire about the technical implementation of phrase matching, particularly regarding the handling of stop words. Some suggest potential optimizations to minimize index bloat while preserving accuracy.

  • Developer Response: The developer clarifies that removing stop words is a deliberate choice, acknowledging the potential for increased index size but emphasizing that the benefits outweigh the drawbacks in this context. They explain that incorporating stop words as an optimization within their advanced search engine framework would introduce unnecessary complexity without significant performance gains.
