Abstract

fetched live from OpenAlex

The real-time search problem requires making ingested documents immediately searchable, which presents architectural challenges for systems built around inverted indexing. In this paper, we explore a radical proposition: What if we abandon document inversion and instead adopt an architecture based on brute force scans of document representations? In such a design, "indexing" simply involves appending the parsed representation of an ingested document to an existing buffer, which is simple and fast. Quite surprisingly, experiments with TREC Microblog test collections show that query evaluation with brute force scans is feasible and performance compares favorably to a traditional search architecture based on an inverted index, especially if we take advantage of vectorized SIMD instructions and multiple cores in modern processor architectures. We believe that such a novel design is worth further exploration by IR researchers and practitioners.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
