protected SeqSpanWeight(SeqSpanQuery query, IndexSearcher searcher) throws IOException {
super(query);

this.field = terms[0].field();
if (positions.length < 2) {
throw new IllegalStateException("PhraseWeight does not support less than 2 terms, call rewrite first");
} else if (positions[0] != 0) {
throw new IllegalStateException("PhraseWeight requires that the first position is 0, call rewrite first");
}
final IndexReaderContext context = searcher.getTopReaderContext();
states = new TermContext[terms.length];
TermStatistics termStats[] = new TermStatistics[terms.length];
for (int i = 0; i < terms.length; i++) {
final Term term = terms[i];
states[i] = TermContext.build(context, term);
termStats[i] = searcher.termStatistics(term, states[i]);
}
