Please add filters to search to allow filtering by module or package name

To see the problem, search "transform" on https://jetbrains.github.io/kotlin-wrappers/.

Describe the solution you'd like

The search should have the option to filter by module or package. I would advocate for searching within the module by default, which could be turned off. So, for example, if I search "transform" inside https://jetbrains.github.io/kotlin-wrappers/kotlin-css/index.html, I should see only kotlin-css results.
