I'm trying to achieve a document hierarchy like so, where the parent is the 'Bundle' and the children are 'Products':
Bundle:
id
imageUrl
Products:
[
id:2
type:"t-shirt"
sizes:[S,M,L]
colors:[blue],
id:3
type:"hoodie"
sizes:[M]
colors:[red]
]
So that I can support queries like "M blue products where imageUrl=xyz".
I've configured my managed-schema.xml like so:
<field name="_root_" type="string" docValues="false" indexed="true" stored="false"/>
<field name="image_url" type="text_en" uninvertible="false" indexed="false" stored="true"/>
<field name="id" type="string" multiValued="false" required="true" stored="true"/>
<fieldType name="_nest_path_" class="solr.NestPathField"/>
<field name="_product_" type="_nest_path_">
<field name="id" type="string" multiValued="false" required="true" stored="true"/>
<field name="type" type="string" indexed="true" stored="true"/>
<field name="colors" type="strings" multiValued="true" indexed="true" stored="true"/>
<field name="sizes" type="strings" multiValued="true" ndexed="true" stored="true"/>
</field>
And I'm indexing the document in Java like so:
SolrInputDocument parent = new SolrInputDocument();
parent.addField("id", bundle.id);
parent.addField("imageUrl", bundle.imageUrl);
for (Product product : bundle.products) {
SolrInputDocument child = new SolrInputDocument();
child.addField("type", product.type);
child.addField("colors", product.colors);
parent.addChildDocument(child);
}
But when I try to index, I'm receiving "org.apache.solr.common.SolrException: ERROR: [doc=347] multiple values encountered for non multiValued field colors: [Black, Deep Royal, Navy]".
Did I structure my children documents correctly?
