Let's assume we have a website allowing you to search for companies not only using key words but also using a geographical location. In the real world, companies tend to have more than a single location. This is where we hit a limitation in the default spatial field used by Solr; we can only have a single location indexed using it. So, we have to create multiple documents for each company location and use group collapsing, or we can use a different field type that allows multivalued location fields. The recipe will show you how to do the latter.
The following steps will take you through the process of enabling the indexation of multivalued spatial fields.
First, we need to prepare our index structure by adding the following section to the
schema.xmlfile:<field name="id" type="string" indexed="true" stored="true" required="true" /> <field name="name" type="text_general" indexed="true" stored="true" /> <field name="loc" type...
