Retrieval Models

Filter by Scope

Scope filters run before ranking in a source-bound retrieval model. 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.

Filter before ranking

The stated process applies scope filters first. Rows outside the requested jurisdiction or source type are not ranked for this query.

filter→rank\text{filter}\to\text{rank}

Example scope request

The query is deadline counting. The scope asks for US-FED jurisdiction and source type rule.

scope=jurisdiction plus source type\text{scope}=\text{jurisdiction plus source type}

Only passing rows enter the rank list

The filter leaves 1 row to rank. That row cites Fed. R. Civ. P. 6(a)(1) and receives rank 1 inside that filtered set.

Diagram note

The table marks pass and fail rows before rank. The scope label is a retrieval filter, not an authority claim.

Summary

Scope filtering keeps a toy search workflow honest by showing which records were excluded before ranking.
