A 311 team searching for dumping also wants illegal fill, but not the city's recycling FAQ. Which operator combination should they apply?
Select an answer to reveal the explanation.
Short Explanation
Dumping and illegal fill are two street names for a similar mess, and the recycling FAQ is the neighbor who keeps answering the wrong doorbell. OR gathers the synonyms; a minus-term shows the FAQ the door. Autocomplete is not a Boolean strategy.
Full Explanation
Combine an OR-class operator for civic synonyms such as dumping and illegal fill with a minus-term to drop known recycling FAQ noise. That pairing expands relevant 311 vocabulary while suppressing a predictable irrelevant page class. Searching only the recycling FAQ and treating it as the dumping corpus points at the wrong document set. Requiring every synonym and the recycling term together so nothing is missed forces noise into every hit. Disabling operators and relying on autocomplete suggestions abandons control over inclusion and exclusion. Exam caveat: minus-terms can over-suppress if the excluded string appears on relevant pages—review a sample of removed hits. Operational check: save the Boolean-style query, spot-check the first pages for both synonym coverage and absence of the recycling FAQ, then adjust exclusions carefully. Keep the civic purpose, method limits, and exhibit labels aligned so reviewers can see what was public-source work versus other authorities. Document residual uncertainty explicitly rather than implying completeness. Prefer reversible public methods and preserve exhibits that a second analyst can reopen without guessing. When sources conflict, record both locators and state the confidence level in plain language.
