```
query = query.replace(/^[-:{}[\]*^()|"]+|[-:{}[\]*^()|"]+$/g, '');
```
This pattern is composed of:
```
^[CHARS]+|[CHARS]+$
```
where `CHARS` are the characters you want to remove.
* `^[CHARS]+` - Match one or more of those characters at the beginning of the string
* `|` OR ... | In case you cannot easily understand regex, you can do another way (still ugly, but maybe better than yours. Not tested.):
