Golang Mongodb模糊查询的使用示例

db.article.find({"title": {$regex: /a/, $options: "im"}})

query := bson.M{"title": bson.M{"$regex": "a", "$options": "im"}}

// RegEx represents a regular expression. The Options field may contain
// individual characters defining the way in which the pattern should be
// applied, and must be sorted. Valid options as of this writing are 'i' for
// case insensitive matching, 'm' for multi-line matching, 'x' for verbose
// mode, 'l' to make \w, \W, and similar be locale-dependent, 's' for dot-all
// mode (a '.' matches everything), and 'u' to make \w, \W, and similar match
// unicode. The value of the Options parameter is not verified before being
// marshaled into the BSON format.
