Description

Passing an empty string as query value will avoid triggering a search to allow optional chaining such as this:

      this.total = (await this.$content('people')
          .search('')
          .only([])
          .fetch()).length

Docs have been updated in FR & EN. JA & RU update necessary.

I went for an explicit false parameter but maybe it would be more elegant and concise to skip the search if there is no parameter or an empty string. It can be fixed, let me know.

What about an empty string @Billybobbonnet, doesn't it work with it?

In the current version, nope.

I updated my PR to fix this.
