[CLucene-dev] MultiSearch How to?

[Mohammad i. <m.i...@gm...>]

Hi,

I have a problem in searching multiple indexes.
We have two options to do this
*1- using MuliSearcher*
with this option i always get hits from the second index only however i use
MultiSearcher::subSearcher(int32_tn)  to be sure that the hit is from 
the index number (0)
here is a code sample
Searchable*s[3]={newIndexSearcher(firstIndexPath),newIndexSearcher(secondIndexPath()),NULL};
MultiSearcher * searcher  = new MultiSearcher(s);
Hits * hits = searcher->search(query);
for(int i = 0; i < hits->length(); i++){
cout<<searcher->subSearcher(i);
}

The Result is
0
0
1
1

So it means that i have hits from each index, but when i try to get the 
docs i always found that the docs came from the second index!

*2- Using MultiReader*
with this option i couldn't make the app to compile.
here is a code sample
         
lucene::util::Array<IndexReader*>*r=newlucene::util::Array<IndexReader*>(3); 


     r[0]  =  IndexReader::open(firstIndexPath);

     r[1]  =  IndexReader::open(secondIndexPath);

     r[2]  =  NULL;

     MultiReader  *  multiReader  =  new  MultiReader(r);

m_searcher=newIndexSearcher(multiReader);

I always get an error
error: invalid conversion from 'lucene::index::IndexReader*' to 
'unsigned int'

How can I search multiple Indexes?

Sincerely,
