public UnionDocsAndPositionsEnum(Bits liveDocs, AtomicReaderContext context, Term[] terms, Map<Term,TermContext> termContexts, TermsEnum termsEnum) throws IOException {
  List<DocsAndPositionsEnum> docsEnums = new LinkedList<>();
  for (int i = 0; i < terms.length; i++) {
    final Term term = terms[i];
    TermState termState = termContexts.get(term).get(context.ord);
    if (termState == null) {
      // Term doesn't exist in reader
      continue;
    }
    termsEnum.seekExact(term.bytes(), termState);
    DocsAndPositionsEnum postings = termsEnum.docsAndPositions(liveDocs, null, DocsEnum.FLAG_NONE);
    if (postings == null) {
      // term does exist, but has no positions
      throw new IllegalStateException("field \"" + term.field() + "\" was indexed without position data; cannot run PhraseQuery (term=" + term.text() + ")");
    }
    cost += postings.cost();
    docsEnums.add(postings);
