about searching | 比利时vs摩洛哥足彩

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).
