-The Search Line can contain wildcard symbols `?` (matches any one character), `*` (matches any characters number) or ranges of characters `[...]`. To find characters `?`, `*`, `[` and `]` it should be escaped with backslash like `\?`, `\*`, `\[`, `\]`.

+| `*`      | Matches zero or more of any characters.                                |
+| `[abc]`  | Matches one character given in the bracket.                            |
+| `[a-c]`  | Matches one character from the range given in the bracket.             |
+| `[!abc]` | Matches one character that is not given in the bracket.                |
+| `[!a-c]` | Matches one character that is not from the range given in the bracket. |

-    The wildcard symbol at first position in word leads to full headwords list scanning and it may take a long time for huge dictionaries.
