 ### Special characters {#basic-rules-special-characters}
 
-- **`*`** — a wildcard character. It is used to represent "any set of characters". This can also be an empty string or a string of any length.
-- **`||`** — matching the beginning of an address. With this character you do not have to specify a particular protocol and subdomain in address mask. It means, `||` stands for `http://*.`, `https://*.`, `ws://*.`, `wss://*.` at once.
+- **`*`** — a wildcard character. It is used to represent any set of characters. This can also be an empty string or a string of any length.
+- **`||`** — an indication to apply the rule to the specified domain and its subdomains. With this character, you do not have to specify a particular protocol and subdomain in address mask. It means that `||` stands for `http://*.`, `https://*.`, `ws://*.`, `wss://*.` at once.
 - **`^`** — a separator character mark. Separator character is any character, but a letter, a digit, or one of the following: `_` `-` `.` `%`. In this example separator characters are shown in bold: `http:`**`//`**`example.com`**`/?`**`t=1`**`&`**`t2=t3`. The end of the address is also accepted as separator.
 - **`|`** — a pointer to the beginning or the end of address. The value depends on the character placement in the mask. For example, a rule `swf|` corresponds to `http://example.com/annoyingflash.swf` , but not to `http://example.com/swf/index.html`. `|http://example.org` corresponds to `http://example.org`, but not to `http://domain.com?url=http://example.org`.
