## Analysis of Realistic Search Pattern
This log demonstrates the reality of searching a sparse corpus:
1. **High duplicate rate** - The same claims appear in multiple searches
1. **Topic bleeding** - Searches like “waters” or “illegal” return mostly irrelevant results
1. **Geographic clustering** - Most claims are UK-focused despite global corpus
1. **Source concentration** - FullFact.org dominates fishing-related fact-checks
1. **Temporal gaps** - No 2024 claims; concentration around Brexit events (2016, 2020-2021)
1. **Entity success** - Country names (Spain, Norway) more successful than generic terms
1. **Pattern emergence** - Clear claim templates emerge even from limited data
1. **Dataset availability** - More datasets than factchecks for fishing topics
The search evolved from broad single words to targeted entity+keyword combinations, ultimately extracting a network of ~22 unique fishing-related claims from ~42 searches - a realistic yield from a sparse global corpus.
