The open-data officer asks why two search engines return different hits for the same site-restricted query. How should the analyst explain it?
Select an answer to reveal the explanation.
Short Explanation
Search engines are different librarians with different card catalogs—not a single omniscient archive. If one misses a city PDF, another may have crawled it. Run more than one class; do not crown an oracle.
Full Explanation
Each search engine maintains an incomplete, independently crawled index, so identical operators can yield different civic hits. Fundamentals OSINT therefore uses more than one engine class before concluding a document is absent. Result differences do not imply deception, exclusive municipal indexing, or illegal operators. Note which engine returned which URL when the sets diverge.
