Hi O.O., You don't need to add them all into the schema. You can use the wildcard fields like <dynamicField name="*_s" type="string" indexed="true" stored="true" /> to hold them. You can then have the attribute name be the part of the wildcard and the attribute value be the field contents. So you could have fields like Function_s:Scanner etc and then you could ask for facets which are relevant based upon query or category.
That would be a much more straightforward approach and much easier to facet on. Hope that helps a little bit. -Robi -----Original Message----- From: O. Olson [mailto:olson_...@yahoo.it] Sent: Monday, January 28, 2013 1:42 PM To: solr-user@lucene.apache.org Subject: Solr Faceting with Name Values Hi, We are looking at putting our Product Catalog into Solr. Our Product Catalog involves a Product, and a number of [Name, Value] pairs – which represent attributes of a particular product. The attribute names are standard along a certain Product Category, but they are too numerous to put into the schema. I would like to add faceting queries on these attributes. For e.g. Product 1: Name: Cannon Scanner Category: Office Machines Attribute 1 Name: Function Attribute 1 Value: Scanner Attribute 2 Name: PC Connection Attribute 2 Value: USB Attribute 3 Name: Scan Speed (ppm) Attribute 3 Value: 2 Product 2: Name: HP Printer Category: Office Machines Attribute 1 Name: Function Attribute 1 Value: Printer Attribute 2 Name: PC Connection Attribute 2 Value: LAN Attribute 3 Name: Print Speed (ppm) Attribute 3 Value: 35 I would like to know if there would be an easy way to retrieve the Facet Counts related to “PC Connection”. I think this should give me the counts for LAN, USB, Wi-Fi etc. for the way products connect to a PC. If I would put “PC Connection” into a separate field in the schema in Solr, I can append something like the following to the end of my query: &facet=true&facet.field=PC+Connection However, there are too many attribute names like “PC Connection”. Is there any way to get the facet counts without putting “PC Connection” into a separate field? How should I structure my schema to get these results? Thank you all for your help. O.
