Hello there! I trying to query for a specific document on a efficient way.
My index is structured in a way where I have an id field which is a unique
key for the whole index. When I'm updating/removing a document I was
searching for my id using a Searcher and a TermQuery. But reading the list
it seems that its a bit of overhead, using a reader.termDocs(term) would be
faster.
Here's a piece of code:
private void deleteFromIndex(String id){
Term term = new Term("id",id);
IndexReader reader = readerManager.getIndexReader();
TermDocs termDocs = null;
try {
termDocs = reader.termDocs(term);
while(termDocs.next()){
int index = termDocs.doc();
if(reader.document(index).get("id").equals(id)){
reader.deleteDocument(index);
}
}
} catch (IOException e) {
e.printStackTrace();
}finally{
if(termDocs != null){
try {
termDocs.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
problem is, reader is not returning any term. When I switch to query it
works. My documents have all being indexed using BrazilianAnalyzer, don't
know if that could be the reason.
Regards
