Steve Rowe commented on SOLR-4567:
----------------------------------
Here's a version, as of Solr 4.2, of the SOLR-3798 table enumerating all
possible combinations of copyField source and dest value types, expanded to
include Alex's case: copyField source pattern matching explicit field(s) - note
that destination patterns matching explicit field(s) are excluded because they
are nonsensical: the asterisk could create field names that wouldn't be the
same as the explicit field.
The following declarations are matched by the examples in the table below:
{code}
<field name="text" .../>
<field name="title" .../>
<field name="text_en" .../>
<dynamicField name="*_i" .../>
<dynamicField name="*_s" .../>
{code}
||case #||{{source}} value type||{{dest}} value type||Example||Schema parse

[1] A {color:blue}"subset pattern"{color} matches a subset of the language
recognized by a declared dynamic field's pattern
[2] A {color:orange}"subset pattern no asterisk"{color} is one member from the
language recognized by a declared dynamic field's pattern

> Key: SOLR-4567
> URL: https://issues.apache.org/jira/browse/SOLR-4567
> Project: Solr
> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 4.2
> Reporter: Steve Rowe
> Assignee: Steve Rowe
>
> Alexandre Rafalovitch reported on the solr-user mailing list
> [http://markmail.org/message/sqhzxaet55wztldq] that a copyField directive
> that worked under Solr 4.1 has stopped working under Solr 4.2:
> {code:xml}
> <field name="addr_from" type="email" indexed="true" stored="true"
> required="true" />
> <field name="addr_to" type="email" multiValued="true" indexed="true"
> stored="true" required="true" />
> <copyField source="addr_*" dest="text" />
> {code}
> I'm 99% sure that matching multiple explicit fields is not the problem, but
> rather the issue is that I committed changes under SOLR-4503 to handle
> additional previously unhandled changes, but I didn't consider this case, and
> so introduced the regression. [The table on
> SOLR-3798|https://issues.apache.org/jira/browse/SOLR-3798?focusedCommentId=13591583&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13591583]
> that attempted to describe all possible combinations of copyField directives
> does not include this case.
