Support for versioning

[fasolens]

Hi,
I am using versioning in my docs. When I search some string f.ex. firewall, it displays results for all versions.

I have tried to exclude router for versions other then the newest with:

[
      require.resolve('docusaurus-lunr-search'),
      {
        excludeRoutes: [
          'docs/2.4.2/**/*',
          'docs/2.4.1/**/*',
        ]
      }
],

It would be nice to point only to the newest existing document. (It can happen that in new version, some documents are removed), or display version in search results.

I have a similar issue with excludeRoutes, in that it doesn't seem to exclude the paths that I pass in:

    [require.resolve('docusaurus-lunr-search'), {
      excludeRoutes: [ // exclude LXDS materials from search
        'docs/lxds-advanced/**/*',
        'docs/lxds-get-started/**/*',
        'docs/lxds-post-pub/**/*',
        'docs/lxds-publish/**/*',
        'docs/lxds-quickstart/**/*',
        'docs/lxds-standards/**/*', 
      ]
    }]

It still indexes all of those paths. Is there something I'm doing wrong or is this feature broken?

Displaying versions in search results is one possibility, but the most natural choice would be to just search in the scope of a currently selected version. By following this approach, search results won't contain intermixed versions at all thus avoiding any confusion.
