• Search looks for exact, case-insensitive keywords; keywords shorter than a minimum length are ignored.
• Use upper-case OR to get more results. Example: cat OR dog (content contains either «cat» or «dog»).
• You can use upper-case AND to require all words, but this is the same as the default behavior. Example: cat AND dog (same as cat dog, content must contain both «cat» and «dog»).
• Use quotes to search for a phrase. Example: «the cat eats mice».
• You can precede keywords by — to exclude them; you must still have at least one «positive» keyword. Example: cat -dog (content must contain cat and cannot contain dog).
