hello everyone
I have this test code:
IndexReader ir = getReader();
TermQuery q = new TermQuery(new
Term("sub_id",NumericUtils.intToPrefixCoded(57)));
Filter f = new QueryWrapperFilter(q);
try
{
DocIdSet s = f.getDocIdSet(ir);
DocIdSetIterator i = s.iterator();
while(i.nextDoc() != DocIdSetIterator.NO_MORE_DOCS)
{
System.out.println(i.docID());
}
System.out.println(f.hashCode());
System.out.println(s.hashCode());
System.out.println(ir.hashCode());
System.out.println(ir.getFieldCacheKey().hashCode());
}
catch (IOException e)
{
e.printStackTrace();
}
1. getReader() returns a MultiReader may consist of several
IndexReaders, in my test case ,only consist of one IndexReader
2. index files won't change
assuming that index files won't be updated, and my question is :
1. why ir.hashCode() returns different value every time I run this
code?
2. if I copy the index file to another server ,and they provide search
service together,will f.getDocIdSet(ir) return the same DocIdSet? if true,how
to cache filter results and share between the 2 servers? how to form a cache
key not influenced by question 1?
Thanks ~~
