Jan Høydahl commented on SOLR-3045:
-----------------------------------
Alternatively, Hoss' suggestion from SOLR-3026, with per-field override syntax
for the virtual fields that will cause DMQ sub-queries. I like this syntax
better than mine :)
{noformat}
q=elephant title:dumbo who:george
&qf=title^3 firstname lastname^2 description^2 catchall
&uf=title^5 who^2 *
&f.who.qf=firstname lastname^10
{noformat}
> eDismax: Allow virtual fields
> -----------------------------
>
> Key: SOLR-3045
> URL: https://issues.apache.org/jira/browse/SOLR-3045
> Project: Solr
> Issue Type: New Feature
> Components: search
> Reporter: Jan Høydahl
>
> 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.
