Re: what kind params should be in "pf" , pls give a demo.

pf has the format as qf.

<pf>titlePhrase^10.0</pf>

For our project, if user query text matches the title of an article/book, we
want to surface that article as the first result. So, we are using pf field
to give additional boost to results that have the exact title match.

: pf has the format as qf.
: 
: <pf>titlePhrase^10.0</pf>

...uh, i'm not sure what that xml syntax is suppose to convey, but if you 
are putting it in a solrconfig file as a default it would be...

  <str name="qf">titlePhrase^10.0</str>

Note also that Dickens qf is also malformed...

: >  <str name="qf">'pSubject^2 pContent^1.5' </str>

...those single quotes should not be there...

   <str name="qf">pSubject^2 pContent^1.5</str>
