Hi.
I have a question about retrieving information.
Lets say I have an index which contents a millions of documents with 2-3
small fields an a 10 large fields.
Then I run a query which returns me a 1000 of hits. But I am interested
only one small field, and I don't want to load other fields.
Can I do something like what?
int id = hits.id(n);
FieldSelector fieldSelector = new FieldSelector() {
public FieldSelectorResult accept(String fieldName) {
if(fieldName.equals(field))
return FieldSelectorResult.LOAD_AND_BREAK;
return FieldSelectorResult.NO_LOAD;
}
};
Document doc = reader.document(id, fieldSelector);
if(doc == null)
throw new IOException("Document with id "+id+" not found");
return doc.get(field);
n from 0 to hits.length().
Best regards,
Sergey
