In Yandex to look for complex expressions with special characters?

It took the network to find material on to a snippet are not able to digest the lessphp library.
Literally the line of the error was the following:
parse error: failed at `(~".span@{index}") { .span
I have put in Yandex, and... nothing decent is not found.

Used the link "search in Google" — there are no such problems arose and the first 2 recordings were the desired material.

Resented this situation and started to try to feed Yandex different options (I tried to enclose the phrase or the part in quotation marks, etc.), but to no avail.

The question is, is there any way to delete this Yandex, or it is in principle similar no indexes or indexes on another?

Use Google.
Google only recently learned to look for special characters, Yandex yet can not.

In Yandex have not tried it, but Google sometimes helps deleting all special characters. The remaining meaningful words is often possible to find something.
