I don’t recommend this plugin

I installed this plugin in order to facilitate the search when looking for something that was in the content of a document. However, from the moment I installed this plugin, whenever I add a new document to the website, it is very slow because it is running the indexing simultaneously with the upload. I was told that it would be possible to have the plugin do the indexing asynchronously and that it would take a few days. However, months have passed and still no answer. Still with regard to this matter, whenever I tried to talk to them, which happens almost daily, no one answered me.
