Hi there, I am indexing documents created from pdf files. These files are processed and broken down to pages with text contained on them. Sample document looks like this: {:name =\> "A name", :attachments =\> [ {:name =\> "first attachment", :pages =\> [ {:number =\> 1, :text =\> "page 1 contents"}, {:number =\> 2, :text =\> "page 2 contents"}, ] ]} When I search for text with highlights i get response with field :highlight =\> {"attachments.pages.text" =\> array\_of\_fragments}. Now the problem is, that I lose information about on which page/ attachment the highlight is in. (Or any other possible page fields.) I've also tried creating/indexing pages as separate documents, where i get all the fields back. However by doing so I cannot find a way to group them by attachment\_id/document\_id and thus I lose to ability to score attachments/documents with multiple matching pages better. Any ideas how to solve this? johno ---

Perhaps, you could index pages instead of a full doc containing many pages as you search for pages. Using \_parent / \_childs, you could perhaps make the link between the document and its pages. I didn't do it yet by myself but thinking of it. So I don't know if it will work or not. Hope this could help David 😉 Le 27 juin 2011 à 13:39, johno [johno@jsmf.net](mailto:johno@jsmf.net) a écrit : > Hi there, > > I am indexing documents created from pdf files.

Hi, David. Thanks for the response, but as I written in my first post. I've already tried that, but there is another problem with scoring.

Sorry. Didn't read well the end of your post ☹ shame on me ! So, i have no other idea but I would love to see a solution for that. On my project, we have made a "group" like solution. We have two field : Field1 Field2 We create a EsField which contains the content of field1 + separator + content of field2. Such as content1KKKKcontent2 So if i want documents containing a line with content1 AND content2, we can search for content1KKKKcontent2. I'm not convinced that it can be useful for your use case.
