I experienced the new plugin of WordPress https://fulltextsearch.org/. It creates a transparent word-based index for search, add a relevance, make meta fields and attachment files searchable by their content. The PDF, DOC, DOCX and other formats are supported.That index system smooth the search without overloading the server as well.
