When finding the most relevant search results, it’s important to consider data beyond the Title, Content, and Excerpt which is the only thing native WordPress includes.
Many times the images uploaded to your entries include
alt text, filenames with valuable keywords, and more for example.
SearchWP will also parse your documents and make that content searchable as well! Supported document types include PDFs, Office documents, plain (and rich) text, and more!
WordPress is able to display results from your Media library in the same way it displays results from any other post type, and SearchWP is able to find documents added to your Media library!
Adding document content to search results
Adding document content to SearchWP is a matter of adding the Document Content attribute to Media within a SearchWP Engine:
With that in place you can set the relevancy weight to Document Content and SearchWP will extract content from documents within your Media library and index that content along with everything else that’s been added to the Engine.
SearchWP also allows you to quickly restrict Media results based on file type by taking advantage of Rules:
How do Media results appear?
SearchWP does not modify the way your theme displays search results in any way.
Media (as far as WordPress and SearchWP is concerned) is just another post type entry that has a permalink, Title, and other details that your search results include.
SearchWP’s job is to find those Media results and include them when applicable, your theme will display a Media result in the same way it does any other post type result.
