How to Read Data Clawled by nutch1.5 and Search keywords(2)

[??????]

Hi ,
     Firstly, I have to make an apology for my mistakes in last email,
  which contained some ambiguity in expression.(I'm non-native speaker)
     Here, I still have problems in these topic. I would like to learn how to
   finish searching by using the api in nutch. I don't want to install and 
config
   solr. So , I need helps to get more informations and some examples.
     Thanks for your help.
