[jira] [Issue Comment Edited] (SOLR-3026) eDismax: Locking down
which fields can be explicitly queried (user fields aka uf)
[ https://issues.apache.org/jira/browse/SOLR-3026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13199240#comment-13199240 ]

------------------------------------------------------------
Super duper. I tested it and it works great! Strange, I could not get aliasing for qf fields to work before now. Now it works like a charm.
A possible optimization would be to detect if the f.who.qf= contains just a single field, and create a simple TermQuery(?) instead of a DisMaxQuery in that case. But it might not be important for performance..
Another thing to re-consider is whether the default should be {{uf=\*}} or {{uf=-\*}}. If we aim to let edismax replace dismax, people may want it to behave like dismax out of the box. But if it won't replace dismax it's better to stick with the current defaults which people already are used to. Note that since eDismax is still @lucene.experimental we should not be afraid to change defaults.
