You'll need to run two queries. One for the user's query. Then if you need to get the related books, collect all the related books from the results, build a second query that will query the BookId field for all the related books (create an OR query for all the related bookIDs).
Then merge the results from the two queries (manually) Aviran http://www.aviransplace.com -----Original Message----- From: Dragon Fly [mailto:[EMAIL PROTECTED] Sent: Monday, June 12, 2006 10:30 AM To: java-user@lucene.apache.org Subject: Related documents ... Hi, I have an index that contains 3 fields: Book Id, Book Title, and Related Book Ids. For example: ===== Book Id Book Title Related Book Ids A0001 Title 1 A0003, A0004 A0002 Title 2 A0003 Title 3 A0001, A0002 A0004 Title 4 .... .... ===== Note that the related book id field can be empty. My application allows the users to search for a book title and optionally return the related books. For example: (Book Title = "Title 3") and (Return Related Books = false) This should return the Lucene document for A0003 only and can be implemented easily. (Book Title = "Title 3") and (Return Related Books = true) This should return the Lucene documents for A0003, A0001, and A0002. What is a good way to implement this? Thank you. _________________________________________________________________ Express yourself instantly with MSN Messenger!
