Hi, I have question regarding nested document queries: For example, let’s say that I have the following book: Book _title: Nested document for dummies Chapter1_Title: Introduction Chapter1_Content: Nested documents are fun. Chapter2_Title: Which technology should I use? Chapter2_Content: Lucene of course!
First I want to find books that contain an introduction and that are about Lucene. So I decide to flatten my data and use 3 multivalued fields (Book_Title,Chapter_Title and Chapter_Content), I index my document and then I get what I want when I use the following query : “ chapter_title:Introduction AND chapter_title:Lucene “ Now I want to find books that contain “fun” in a chapter called “introduction”. My model is no more valid (Chapter2_content is no more linked with Chapter2_title). That is why I change my datamodel and use nested documents: I have now a parent with a single valued field Book_title and different childs with single valued fields Chapter_title and Chapter_Content. Now, when I run the query “chapter_title: Introduction AND chapter_content:fun” I also get what I want… But what do I have to do if I want to use these two kinds of query with a unique data model?
Thank you, Regards, Aurélien MAZOYER --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
