i'm having trouble narrowing my search booleans say i want to search for "conservation of energy" AND "Kepler's second law" seems well enough in english.... i dont want to result with conservation or of or energy or kepler or second or law.... but what am i doing wrong? do i need parenthesis instead of quotes? i guess i need to check fundamentals also... is the 'space' (bar) equal to OR... are quotes usable for exact phrases does AND have to be capitalized can i use + for and...which for or? minus? how about ~ for not or is it allowed or ¬ or just NOT and alas, wildcards...the texas poker of search parameters. The forum is great, I am looking for lots of help with my personal research and hope many topics are at least casually, but vey much sometimes technically treated. i cant get to them if i cant search more specifically. I am certain some forums by the same software are getting different search boolean treatments, but then, if i'm not doing it right, i would not filter that properly, either! I have been a senior analyst. the booleans of internet web searching and forum searching are a little differet than pure math or even COBOL IF statements, or VB or...or...oh no i said "or"....[btw, dont say 'or' to ben hur...] i'd rather be getting no results for being too specific than getting too many results for me to survey. at least then i could know to start a new thread!
