# Search by date, language, and file type

To refine search results, you can use the file type, language, and publication date operators.

Typically, the operator is specified after the text of the search query and is separated from it by a space. You can use multiple operators in the same query, separating them with a space. If an operator itself contains a space, replace it with the `%20` character combination.

When using operators where the hostname is a parameter (`url`, `host`, or `rhost`), enter the [primary site address](https://yandex.com/support/webmaster/yandex-indexing/site-mirrors.xml). For example,  [host:archive.org], not [host:www.archive.org]. You can [add a host](https://webmaster.yandex.com/sites/add/) to the Yandex database to find out whether a specific address is the primary one.
