I thought that a similarity class will only affect the scoring of a
single field.. not across multiple fields? Can anyone else chime in with
some input? Thanks.

Hi Mark,
Eh, I don't have Lucene/Solr source code handy, but I *think* for that you'd
need to write custom Lucene similarity.

Subject: Searching multiple fields
I have a use case where I would like to search across two fields but I do not
want to weight a document that has a match in both fields higher than a
document that has a match in only 1 field.
For example.
Document 1
- Field A: "Foo Bar"
- Field B: "Foo Baz"
Document 2
- Field A: "Foo Blarg"
- Field B: "Something else"
Now when I search for "Foo" I would like document 1 and 2 to be similarly scored however
document 1 will be scored much higher in this use case because it matches in both fields. I could
create a third field and use copyField directive to search across that but I was wondering if there
is an alternative way. It would be nice if we could search across some sort of "virtual
field" that will use both underlying fields but not actually increase the size of the index.
Thanks
