I have a two-dimensional array (array of arrays) in my source documents, something like this:

"tagArray": [
   [ "reactjs", "vue.js", "redux" ],
   [ "django", "flask", "python" ],
   [ "ruby", "ruby-on-rails" ]
]

I would like to define this field in Typesense schema, but can not figure out the correct syntax. The idea is to index all the strings in "tagArray" and to control things like stemming, etc.
