Yeah, this is is unfortunate. Would be nice to have both support for payloads and spans in Solr. -Grant
How to use Payloads with Solr?
Hello community, since I have searched for a solution to get TermPositions in Solr, I became more aware of the "payload"-features. So I decided to learn more about payloads. In the wiki, there is not much said about them, so I will ask here at the mailing-list. It seems like Payloads are some extra-information for tokens, which I can customize in any way. For example, I could write a payloadFilter that gives the highest scoring-factor to the first token and the lowest to the last one. I also could say "oh, this word is a substantive. Add this as a payload-information: ". However: How do I use these information at query-time? How can I influence the scoring in Solr? I mean, I could write a payload-interpreter (Am I right to do so with AveragePayloadFunction from Lucene 2.9.1?) for scoring. So, if I do so, I can switch the scoring of all substantives without reindexing the payloads by setting there scoring-factor in the schema.xml (of course this will need some more extra-modifications). Can anybody tell me more about how to use payloads with Solr? For all the others, who want to learn some basic-information about payloads, I would suggest to read this article from Grant Ingersoll: http://www.lucidimagination.com/blog/2009/08/05/getting-started-with-payloads/ It is a really good tutorial and introduction to this topic. Unfortunately, it seems like he has not written anything about how to integrate this in Solr (I haven't find anything more). Kind regards - Mitch P.S. Sorry for double-posting. I had some problems with my mail-account and so there were some pending posts. It seems like they will pend for the next few years... but if not, excuse it, please. -- View this message in context: http://n3.nabble.com/How-to-use-Payloads-with-Solr-tp679691p679691.html Sent from the Solr - User mailing list archive at Nabble.com.
