I think I got CirrusSearch/Elastica/ElasticSearch running and using it as the main search engine. I also have PdfHandler running on MW 1.31.1 and it's able to generate thumbnails and text files of the uploaded PDF. However, I still don't see contents of the PDF in the search results. Is there something I've missed? A configuration setting or something that I need to enable to include the text of the PDF in the search index?
I hope it's okay, I've cross-posted a similar question in Extension talk:PdfHandler.
