Since T-Nation's search is the weakest part of the site, Google is your best friend for looking up stuff on here. Yes, MODs, your site's search BLOWS.
(search term) site:tmuscle.com
Enter that into Google.
A) "quotations" - exact phrase
e.g. "gut health" will look for GUT HEALTH and not a page with "gut" and "health" separate
B) - (minus, no space, then search term) - means "without that term"
e.g. : "gut health" -poliquin site:tmuscle - find all pages with "gut health" (exact phrase) but no mention of Poliquin
C) OR - find a either one term or the other; I prefer to use parentheses to make it easier to read
e.g. "(gut OR digestive) health" -Poliquin site:tmuscle
Finds all pages with a reference to "gut health" OR "digestive health" (notice the OR operator is within the quotations, meaning GUT or HEALTH, either term only in the phrase "gut health" / "digestive health"
e.g. (Waterbury OR thibaudeau) "training articles" -Poliquin site:tmuscle.com
Finds all pages that have the exact term "training articles" on the page (notice that quotations are important for stating the order of two terms) and a reference to either coach, but never including "Poliquin" on the page
Tip: You CAN use a poster's name as a search term, if you want to find a post by a certain poster. Meaning, if you type in "super saiyan" you will find posts by this poster. The poster's name to the left of their actual post counts as any other text on the page.
Notice that you can "stack" these syntactically.
