False Positive?

Hello,

Please see https://www.justfactsdaily.com/?s=Obama%27s+gun+control+agenda&submit=Search for reference. Notice that the 2nd result titled “Obama’s plan for tackling the deficit” does not contain the word ‘gun’, even though I have the settings to use an ‘AND’ search, the ‘OR’ fallback option is disabled, fuzzy search is off, and the minimum word length to index is set to 3.

Any idea why that result is showing up and how to prevent it from doing so?

Thanks much,

Philip
