java - Getting results of a search - lucene 4.4.0 -

i'm experiencing problems on lucene. i'm querying database. far know indexes ok (i checked lukeall-4.4.0). query constructed following:

                q = query.split(" ");                  booleanquery = new booleanquery();                  //query[] queryy = new query[5 + 5 * q.length];                 query[] queryy = new query[3 + 3*q.length];                  //using text                 queryy[0] = new termquery(new term("designacao", query));                 queryy[1] = new termquery(new term("descricao", query));                 queryy[2] = new termquery(new term("tag", query));                  //using separeted values                 (int = 3, j = 0; j < q.length; i++, j++) {                      queryy[i] = new termquery(new term("designacao", q[j]));                     queryy[++i] = new termquery(new term("descricao", q[j]));                     queryy[++i] = new termquery(new term("tag", q[j]));                  }                  (int = 0; < queryy.length; i++) {                     booleanquery.add(queryy[i], booleanclause.occur.must);                 } 

the query ok. searching "not or" query (a booleanquery) going following:

 +designacao:not or  +descricao:not or  +tag:not or  +designacao:not +descricao:not +tag:not +designacao:or +descricao:or +tag:or 

i'm using simpleanalyser, words not , or not removed. problem can't hits. can have hits if make search lukeall-4.4.0 not code. search method following one:

indexreader reader = indexreader.open(directory1);         topscoredoccollector collector = topscoredoccollector.create(50, true);         searcher = new indexsearcher(reader);         searcher.search(booleanquery, collector);         hits = collector.topdocs().scoredocs;         int total = collector.gettotalhits();         displayresults();  

is there wrong in collecting data or something??

kind regards

piece of cake. problem in construction of query:

for (int = 0; < queryy.length; i++) {     booleanquery.add(queryy[i], booleanclause.occur.must); } 

the booleanclause.occur.must means has exist. thus, terms adding booleanquery must exist (term1 , term2 , term3). correct is:

booleanquery.add(queryy[i], booleanclause.occur.should); 

this way can has exist 1 of terms have added (term1 or term2 or term3).

kind regards
