Search result at next component

[Lee Chunki]

Hi,

I am building a new component and it run a new query depend on previous query 
result.
solrconfig.xml setting is like :

      <arr name="components">
        <str>query</str>
        <str>newComponent</str>
        <str>facet</str>
        <str>mlt</str>
        <str>highlight</str>
        <str>stats</str>
        <str>debug</str>
      </arr>

Do you know how can I get “query component” result at “newComponent”?

I am working with “ResponseBuilder” ( 
http://lucene.apache.org/solr/4_1_0/solr-core/org/apache/solr/handler/component/ResponseBuilder.html#retrievedDocuments)
but could not find any ways :(
because I am not good at JAVA

At least what I want to know is “number of query component result”

Thanks,
Chunki.
