Tomás Fernández Löbbe commented on SOLR-3241:
---------------------------------------------
I found the issue with copyfields as you mentioned Robert. foo is
omitNorms=false, and bar is omitNorms=true. I have a copyfield foo->bar and I
add a document like:
<document boost=X>
<field name=foo>AAAAAA</field>
</document>
This case is fixed by the patch. Testing it, i found a similar situation where
a field1 is a poly type with omitNorms=false, and the subtype if it has
omitNorms=true. In this case, it fails even without a copyfield just by adding
a document like:
<document boost=X>
<field name=poly>AAA,BBB</field>
</document>
I don't know if it makes sense to have a poly field where the subtype have a
different value in the "omitNorms" attribute, probably this should fail even
before the document is added.

> After https://issues.apache.org/jira/browse/LUCENE-3796, it is not possible
> to set a boost to a field that has the "omitNorms" set to true. This is
> making Solr's document index-time boost to fail when a field that doesn't
> omit norms is copied (with copyField) to a field that does omit them and
> document boost is used. For example:
> <field name="author" type="text" indexed="true" stored="false"
> omitNorms="false"/>
> <field name="author_display" type="string" indexed="true" stored="true"
> omitNorms="true"/>
> <copyField source="author" dest="author_display"/>
> I'm attaching a possible fix.
