I have changed the code according to MIGRATE.txt
but now i am getting an error at
public long getCorpCount(Vector <SpanTermQuery> clauses)
{
long count=0;
try {
SpanQuery [] clause= new SpanQuery[clauses.size()];
clause= clauses.toArray(clause);
// SpanNearQuery sq = new SpanNearQuery(clause,1,true);
SpanOrQuery sq=new
SpanOrQuery(clause); error here
Spans spans=sq.getSpans(findFeatures.reader);
while(spans.next()) //here was the error
{
count++;
}
}
catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return count ;
}
the error log is :
please use MultiFields.getDeletedDocs, or wrap your IndexReader with
SlowMultiReaderWrapper, if you really need a top level Bits deletedDocs
