Subject Re: Specifying dynamic field type without polluting actual field names with type indicators
Date Thu, 19 May 2016 13:30:03 GMT

It’s an interesting idea.  Could you make a Solr JIRA?

I don’t know where the field type specification would go, but providing a mechanism to specify
field type for previously non-existent fields, outside of the field names themselves, seems

In the meantime, do you know about field aliasing?  

1. You can get results back that rename fields to whatever you want: see the section “Field
Name Aliases” here: <>.

2. On the query side, eDisMax can perform aliasing so that user-specified field names in queries
get mapped to one or more indexed fields: look for “alias” in <>.
