sort issue in Solr

I want Solr return results by relevancy, but it seems it does not make
sense. For example, partial match does not return before exact match.
Even I enabled term length in schema definition.

 

Is there someone can provide suggestions?

 

For example, I want it return as the following order for keyword "BAC":

BAC                       // exact match before partial match below

BACC                    

 

BACC BAC KK      // one exact match plus partial match return before one
exact match/partial match

BAC BC JJ

 

BACC                    // match with few words returns before match
with more words

BACC KK

BACC JJ MM

 

Thanks,

Robert

Thanks Gora. Inspired by the link, I've solved case 1 by putting it as a
exact match OR prefix match, such as "BAC" OR "BAC*".
But I can not find solution for case 2 and case 3 below.
Is there anyone can provide suggestions?

Thanks,

There are various factors that can affect Solr relevance.
* You should try your query with debugQuery=1 added,
   which will show you how the score of each document
   is being calculated.
* Please also take a look at
