complex query with solrnet

Question

How can I build complex queries like this solr query with solrnet.

q=*:* & fq=(Code1:("N02" +OR+ "N01") +OR+ Code2:"B0") 
  +OR+ (*:* AND -Flg:G) +OR+ Id:"\-30"*

I want to use filter queries

1. with logical operations combined with expression

   ex: all cars ((red or green) or automatic)

2. with not operation

   ex: all cars except white ones

3. with wild card

   ex: all cars with make starting 'mit'

4. with parameters which need to be escaped

   ex: all cars with id starting with '-30'

Answer 1

with logical operations combined with expression

ex: all cars ((red or green) or automatic)

Ans: car_color:( red OR green ) OR car_transmission:( automatic )

with not operation

ex: all cars except white ones

Ans : -car_color:( white ) - is spl char used to donate not in solr query

with wild card

ex: all cars with make starting 'mit'

Ans: car_make:mit* * is a wild char represents 0 or more

with parameters which need to be escaped

ex: all cars with id starting with '-30'

Ans: car_id:( -30* ) - is a spl char in solr so it needs to escaped using \ char
