Multi-valued polyfields - Do they exist in the wild ?
Hi:
We have been keen on using polyfields for a while. But we have been restricted from using it because they do not seem to support Multi-values (yet). I am wondering if there are any Custom implementations or is there any ETA on the Solr releases to include Multivalued PolyFields .
Thanks for the support

(Currency has one value and a dynamic table of currency->conversion.
The field type does the conversion calculations on the fly.)
To pick particular values, you have to do your own search inside the
returned array.

Hello,
The most promising approach for doing this is BlockJoinQuery. Here is the
great intro
http://blog.mikemccandless.com/2012/01/searching-relational-content-with.html.
This query and lowlevel indexing support is implemented in Lucene. Some
work is in progress for Solr https://issues.apache.org/jira/browse/SOLR-3076.
The currently present approaches is wiki.apache.org/solr/Join and Grouping
aka FieldCollapsing.
Regards

Hi Yonik:
Thanks, I am looking a field (example: Currency) which can have
multiple values within a document (I.e. Different currencies and
corresponding conversion rates).
I would like to store that information as part of one multivalued field.
Even better would be a solution that upon queried would be able to return
only the items that satisfy the query. (I.e. When a multivalued field is
queried, that the results are the entries within the multivalued field
that satisfy the query)Š
Is there any magic like that ?
If there is a possibility to store complex fields as multivalued fields,
then maybe I could use the CopyField with a condition to copy only the
content that satisfy a threshold score.
Thanks for the support/answers

Poly-fields should support multi-values, it's more what uses them may not.
For example LatLon isn't multiValued because it doesn't have a
mechanism to correlate multiple values per document.
