ExtraPram Option

[GoogleCodeExporter]

What steps will reproduce the problem?
Hi I want to add following dismax as ExtraParams

defType=dismax

qf=features^20.0+text^0.3

I can add those as ExtraParam but when I try to execute the query its throwing 
exception and I found its for encoding + and ^ this two character. 

Can you please advise me how can i pass qf param as extra instead of boost() by 
field.

Are you still there?

HI,
  I also found this problem.Solr does not accept 'qt=features^20.0+text^0.3' in fact.But it can  accept 'qt=features^20.0&qt=text^0.3'.So I would like to add the query parameters like following:
  ExtraParams = new Dictionary<string, string>()
  {
     {"defType","dismax"},    
     {"qf","features^20.0"},
     {"qf","text^0.3"},
     {"mm","2"}
  }    

But ExtraParams is Dictionary<string,string> and "qt" is a duplicate key.I 
think if ExtraParams is ICollection<KeyValuePair<string, string>> the problem 
can be resolved.

ExtraParams is not a dictionary, please see 
https://github.com/mausch/SolrNet/blob/8a7a58edd409ca9b7a9d9f39db42f7d783f11f6a/
SolrNet/Commands/Parameters/QueryOptions.cs#L109

Please post the stack trace or a failing test that reproduces this.

Hi,
  Thanks for you help!
  I did ignore it's definition.I just saw the example in wiki.The example in wiki like following:
  ISolrOperations<Product> solr = ...
  var products = solr.Query(SolrQuery.All, new QueryOptions {
        ExtraParams = new Dictionary<string, string> {
                {"qt", "dismax"}
        }
 });
 So I used Dictionary<string,string> and then I got an error message.

@Thomas.Liu please post the stack trace for the exception you get when defining 
qf.

I think this is not a defect because Solr does not support that expression.If 
you want to search terms or phrases in multiple fields you should split that 
into multiple sub expressions.For example 'qt=features^20.0+text^0.3' should be 
split into 'qt=features^20.0' and 'qt=text^0.3'.'pf' is same.

Solr *does* support multiple fields with boost in single 'qf' parameter just 
fine. BTW I'm assuming you mean 'qf' and not 'qt' which is a very different 
parameter. 
I suspect you are url-encoding the parameter yourselves, which you shouldn't 
 do. But I really need a failing test or at least a stack trace to confirm, otherwise I can only guess...

@Thomas.Liu I need the Solr stack trace when you issue a qf with multiple 
fields, not the SolrNet stack trace when you have a dictionary with multiple 
keys.

Oh,I made a mistake.Solr does support multiple fields.I have found out the 
reason.I used 'qt=features^20.0,text^0.3' to query instead of 
'qt=features^20.0+text^0.3'.So I get the error message as following:

That's my mistake. You can omit it.

@Thomas.Liu can you confirm that an ExtraParams with Dictionary<string,string> 
{{"qf", "features^20 text^0.3"}} (note SPACE and not '+' or ',') works 
correctly so I can close this issue? Thanks...

I have confirmed that.It's OK!
