Hey,

I'm running solr (3.5.0.2011.11.30.16.37.06) and have encountered what  
I think is a bug with the boost function (bf) parameter.

I've used sunspot (for use of solr with rails) which allows managing  
dynamic fields, which by default creates fields like  
"dynamicfield:value1","dynamicfield:value2", though using the :  
character in the field name, which needs to be escaped.

If I use a query which includes "q=dynamicfield\:value1:6", everything  
works fines and matches are found.

However, if I use the bf field with bf=dynamicfield\:value1, I get an  
error message "undefined field dynamicfield", the same without  
escaping the :

Should I file a bug report?

Best,

Nils

Yeah, a bug report would be good.  But really this is a Sunspot bug report.  Field names should NOT have :'s in them.  Field names should stick to standard Java identifier rules, otherwise it's escaping madness.  

You could try something like this as a workaround:

   bq=_val_:"dynamicfield\:value1"

I don't know if that'll do better than the bf issue you've hit, but it's another way of doing the same sort of thing.

Quoting from the new trunk example schema:

"field names should consist of alphanumeric or underscore characters only
and
      not start with a digit.  This is not currently strictly enforced,
      but other field names will not have first class support from all
components
      and back compatibility is not guaranteed."

In other words, don't do it. Replace the colon with an underscore in your
field names.

I think there is a way in sunspot to give an explicit name to a field so
that sunspot doesn't generate <class-name><colon><field-name> for field
names. I think it is the ":as" function, such as:

string :name, :as => :name_s

So, you can then refer to "name" in your ruby code and "name_s" will be the
field name in Solr.
