Retrieval Models

Lexical Match

Token overlap can be counted with exact integer counts. Honesty note: simplified toy corpus; jurisdictions vary; the pinned first step states the as-of date; not legal advice; retrieval points to sources and does not answer the legal question.

Match by token overlap

The stated retrieval model uses exact token overlap. It counts shared tokens between the query and each corpus row.

overlap count=matching tokens\text{overlap count}=\text{matching tokens}

Example query and source row

The example query is diversity amount citizenship. The matching row is the record for 28 U.S.C. sec. 1332.

query tokens are derived\text{query tokens are derived}

The count governs rank order

Record id diversity has 3 of 3 matching tokens and rank 1 in this toy table.

rank=1,match=3 of 3\text{rank}=1,\quad \text{match}=3\text{ of }3

Diagram note

The diagram displays integer overlap and deterministic rank. It does not claim legal relevance or source weight.

Summary

Lexical matching is useful because each displayed number can be recomputed from the query and corpus text.
