Sphinx-tabs only support sphinx<4 :(

Sphinx-tabs only support sphinx<4 :(

there is a pr for sphinx-tabs which im expecting will land when sphinx4 comes out of beta

im wondering whether the stemmer fix could be applied outside of the sphinx4 upgrade - altho hopefully it will come out of beta soon

@phlax how about apply this patch by hand before deploy docs?

how about apply this patch by hand before deploy docs?

it doesnt currently pass CI - besides i would rather wait until sphinx 4 is out of beta before landing that - i think it will make life easier with extensions etc

fixing the stemmer - ie the fix here sphinx-doc/sphinx#8070 - maybe we can include what it does - not sure what is required to do that, or the cleanest way - i can check this further - its possible it could be included using a search adapter

hopefully sphinx4 will be stable soon

Got it, let's wait.
