I found it surprising that the following search terms all return no results:<p>'generate uniform -1 to 1'<p>'uniform -1 to 1'<p>'bbc -1 to 1'<p>'google -1 to 1'<p>'-0 to 0'<p>But<p>'-1 to 1'<p>'X -1 to 1'<p>'0 to 1'<p>'1 to 0'<p>Work. Curiously<p>'-1 to 1' works<p>'-0 to 0' doesn't.<p>Does anybody have some working theories for why this might be?
The minus sign excludes a term, for example "-Dell laptop" would result laptops where "Dell" isn't in the results.<p>By searching "-1 1" you're searching for the term "1"and then excluding all results with the term" 1".
