Online search results useless when searching strings composed of multiple generic words

Simple example:

If I want information about the `--build-order` option of conan info, I'll have a hard time, as it returns all the results for `build`, for `order`, for `BUILD_ORDER` and, hidden, the result for `build-order`. When one looks for options that use very generic names, things can get even worse.

This may be a sphinx bug, or configuration problem? Or maybe there are some search quoting options I'm not aware of? I tried single quotes, double quotes, backquotes, but can't find a way to tell the search engine "don't try to be clever and just search this exact sequence of characters".

Searching `--source-folder` is even worse.
