c# - Iterate through all undeleted Documents in a Lucene (.Net) index -


i want count of un-deleted documents of lucene (.net 2.4) index , read stored fields of or range of these docs. after reading lucene i'm not quite sure, whether indexreader.numdocs() returns count of docs or undeleted ones. can iterate through indexreader.document[] , or contain deleted documents?

if numdocs() , docmuent[] does contain both deleted und undeleted docs suppose i'll have this:

int totalcount = reader.numdocs(); int totalcountundeleted = totalcount; (int idoc = 0; idoc < totalcount; idoc++)   if (reader.isdeleted(idoc))     totalcountundeleted--;  (int idoc = 0; idoc < totalcount; idoc++) {   if (!reader.isdeleted(idoc))   {      document doc = reader.document(idoc);      // read fields   } }

is right way or there other possible way? thanks

this correct way. until optimize index, documents not removed.

alternatively, if have query *:* matches document, can run instead. query method slower, maybe more standard.
