I am relatively new to ElasticSearch. I am using it as a search platform for pdf documents. I break the PDFs into text-pages and enter each one as an elasticSearch record with it's corresponding page ID, parent info, etc.
What I'm finding difficult is matching a given query not only to a single document in ES, but making it match any document with the same parent ID. So if two terms are searched, if the terms existed on page 1 and 7 of the actual PDF document (2 separate entries into ES), I want to match this result.
Essentially my goal is to be able to search through the multiple pages of a single PDF, matching happening on any of the document-pages in the PDF, and to return a list of matching PDF documents for the search result, instead of matching "pages"
