qf with multiple fields triggers what is known as a dismax or DisjunctionMax
query. It matches a document if ANY of the listed fields contains the query
term - checking each term one at a time. So, if you search for three terms
with three different fields in qf, the terms may occur in different fields,
so that they won't necessarily all appear together in any individual field.
Give us an example document that you think is not being matched properly.
Best to try it and reproduce it with the Solr example, if possible.
And, most importantly, best to start every query by writing it in clear,
concise, and complete English - it can be a lot easier to debug a query if
we know what the original intent is.

Subject: Re: AND Queries
When I send that query:
select?pf=url^10+title^8&fl=url,content,title&start=0&q=lang:en+AND+(cat+AND+dog+AND+pencil)&qf=content^5+url^8.0+title^6&wt=xml&debugQuery=on
It is debugged as:
+(+lang:en +(+(content:cat^5.0 | title:cat^6.0 | url:cat^8.0)
+(content:dog^5.0 | title:dog^6.0 | url:dog^8.0) +(content:pencil^5.0 |
title:pencil^6.0 | url:pencil^8.0))) (url:"cat dog pencil"^10.0)
(title:"(cat dog pencil)"^8.0)
Why default field is not applied at this situation?

It's because when you don't specify any field, it's the default field
which is used.
So,
lang:en AND url:book AND pencil AND cat
is interpreted as :
ang:en AND url:book AND <default_field>:pencil AND <default_field>:cat
The default search field is defined in your schema.xml file
(defaultSearchField)
