Yes, exactly.

There is an code example at [1], but you can constraint the position of 
a cell query with the method SirenCellQuery#setConstraint

final  SirenCellQuery scq =new  SirenCellQuery();
scq.add(new  SirenTermQuery(new  Term(DEFAULT_FIELD, term)), SirenCellClause.Occur.MUST);
scq.setConstraint(cell);

final  SirenCellQuery scq1 =new  SirenCellQuery();
scq1.add(new  SirenTermQuery(new  Term(DEFAULT_FIELD, "work")), SirenCellClause.Occur.MUST);
scq1.setConstraint(0);

final  SirenCellQuery scq2 =new  SirenCellQuery();
final  SirenPhraseQuery spq =new  SirenPhraseQuery();
spq.add(new  Term(DEFAULT_FIELD,"my"));
spq.add(new  Term(DEFAULT_FIELD,"city"));
scq2.add(spq, SirenCellClause.Occur.MUST);
scq2.setConstraint(2);

final  SirenTupleQuery tq =new  SirenTupleQuery();
tq.add(scq1, SirenTupleClause.Occur.MUST);
tq.add(scq2, SirenTupleClause.Occur.MUST);
