Reference score185,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Built a finite-state multi-keyword matcher with preprocessing and text scan time linear in input size plus reported occurrences.

Scientific scope

The record is the exact two-author 1975 paper and its stated machine and complexity model. It does not absorb tries, all automata-based matching, or later extensions and implementations.
