Thanks so much Otis. This is working great. Now, I'm trying to make facets on pictures: display doc w/ pic vs. doc w/o pic
To the best of my knowledge, everyone is saying that faceting cannot be done on dynamic fields (only on definitive field names). Thus, I tried the following and it's working: I assume that the stored pictures have a sequential number (_1, _2, etc.), i.e., if pic_url_1 exists in the index, it means that the underlying doc has at least one picture: ...&facet=on&facet.field=pic_url_1&facet.mincount=1&fq=pic_url_1:* While this is working fine, I'm wondering whether there's a cleaner way to do the same thing without assuming that pictures have a sequential number. Also, do you have any documentation about handling Dynamic Fields using SolrJ. So far, I found only issues about that on JIRA, but no documentation. Thanks a lot. -Saïd On Jun 26, 2010, at 1:18 AM, Otis Gospodnetic wrote: > Saïd, > > Dynamic fields could help here, for example imagine a doc with: > id > pic_url_* > pic_caption_* > pic_description_* > > See http://wiki.apache.org/solr/SchemaXml#Dynamic_fields > > So, for you: > > <dynamicField name="pic_url_*" type="string" indexed="true" stored="true"/> > <dynamicField name="pic_caption_*" type="text" indexed="true" > stored="true"/> > <dynamicField name="pic_description_*" type="text" indexed="true" > stored="true"/> > > Then you can add docs with unlimited number of > pic_(url|caption|description)_* fields, e.g. > > id > pic_url_1 > pic_caption_1 > pic_description_1 > > id > pic_url_2 > pic_caption_2 > pic_description_2 > > > Otis > ---- > Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch > Lucene ecosystem search :: http://search-lucene.com/ > > > > ----- Original Message ---- >> From: Saïd Radhouani <r.steve....@gmail.com> >> To: solr-user@lucene.apache.org >> Sent: Fri, June 25, 2010 6:01:13 PM >> Subject: Setting many properties for a multivalued field.
