Re: Item Facet
This is how it goes: 1. You create a dynamic field in the schema called "product_*". This means that while indexing, you can create fields starting with "product_" dynamically for a document. 2. If a document, doc1, is dealing with prod1 and prod2, you create fields called product_prod1 and product_prod2 and populate them with the corresponding "values". 3. If a patch for SOLR-247<https://issues.apache.org/jira/browse/SOLR-247>is committed, you can perform a facet query, as simple as: facet.field=product_*. This should give you results in the manner you expect. product_prod1:all values, product_prod2:all_values and so on ... Hope this helps.

Re: Item Facet
The behavior i'm expecting is something similar to a GROUP BY in a relational database. SELECT product_name, model, min(price), max(price), count(*) FROM t GROUP BY product_name, model The current schema: product_name (type: text) model (type: text) price (type: sfloat) On Fri, Aug 7, 2009 at 11:07 AM, Yao Ge wrote: > > Are your product_name* fields numeric fields (integer or float)? > > > Dals wrote: >> >> Hi... >> >> Is there any way to group values like shopping.yahoo.com or >> shopper.cnet.com do? >> >> For instance, I have documents like: >> >> doc1 - product_name1 - value1 >> doc2 - product_name1 - value2 >> doc3 - product_name1 - value3 >> doc4 - product_name2 - value4 >> doc5 - product_name2 - value5 >> doc6 - product_name2 - value6 >> >> I'd like to have a result grouping by product name with the value >> range per product.

Thanks Avlesh. But I didn't get it. How a dynamic field would aggregate values in query time? On Thu, Aug 6, 2009 at 11:14 PM, Avlesh Singh wrote: > Dynamic fields might be an answer.

Re: Item Facet
Dynamic fields might be an answer. If you had a field called "product_*" and these were populated with the corresponding values during indexing then faceting on these fields will give you the desired behavior. The only catch here is that the product names have to be known upfront. A wildcard support for field names in facet.fl is still to come in Solr. Here's the issue - https://issues.apache.org/jira/browse/SOLR-247 Cheers Avlesh On Fri, Aug 7, 2009 at 3:33 AM, David Lojudice Sobrinho wrote: > I can't reindex because the aggregated/grouped result should change as > the query changes... in other words, the result must by dynamic > > We've been thinking about a new handler for it something like: > > > /select?q=laptop&rows=0&itemfacet=on&itemfacet.field=product_name,min(price),max(price) > > Does it make sense?

Re: Item Facet
I can't reindex because the aggregated/grouped result should change as the query changes... in other words, the result must by dynamic We've been thinking about a new handler for it something like: /select?q=laptop&rows=0&itemfacet=on&itemfacet.field=product_name,min(price),max(price) Does it make sense? Something easier ready to use?

RE: Item Facet
If you can reindex, simply rebuild the index with fields replaced by combining existing fields. -Yao -Original Message- From: David Lojudice Sobrinho [mailto:dalss...@gmail.com] Sent: Thursday, August 06, 2009 4:17 PM To: solr-user@lucene.apache.org Subject: Item Facet Hi... Is there any way to group values like shopping.yahoo.com or shopper.cnet.com do?

Something like: product_name1 - (value1 to value3) product_name2 - (value4 to value6) It is not like the current facet because the information is grouped by item, not the entire result. Any idea?
