Jan Høydahl updated SOLR-3045:
------------------------------
Description:
Imagine a one-field yellow page search using eDisMax across fields
{noformat}
qf=firstname middlename lastname companyname category^10.0 subcategory products
address street zip city^5.0 state
{noformat}
Now this of course works well. But what if I want to offer my users fielded
search on "who", "what" and "where".
A way to do this now is copyField into three new fields with these names. But
then you lose the internal weight between the sub fields.
A more elegant way would be allowing virtual field names mapping to multiple
fields, so user can search where:london and match address, street, zip, city or
state automatically.

A more elegant way would be allowing virtual field names mapping to multiple

{noformat}
&uf=who:firstname,middlename,lastname^2.0,companyname
what:category,subcategory,products where:address,street,zip,city^10.0,state
{noformat}
This could probably be solved by adding each as a dismax sub-Query
One option: Imagine uf extended further:
{noformat}
&uf=who:firstname,middlename,lastname^2.0,companyname
what:category,subcategory,products where:address,street,zip,city^10.0,state
{noformat}
