As of openedx#918 , the content search only allows filtering the results by one tag at a time, which is a limitation of Instantsearch.

So with this change, usage of Instantsearch + instant-meilisearch has been replaced with direct usage of Meilisearch. Not only does this simplify the code and make our MFE bundle size smaller, but it allows us much more control over how the tags filtering works, so that we can implement searching by multiple tags.

Trying to modify Instantsearch to do that was too difficult, given the complexity of its codebase.
