Paul Elschot commented on LUCENE-6308:
--------------------------------------
I'm slowly progressing with this.
There is one change in the test code in TestSpans that nicely shows in a few
lines what this is all about.
It is the code for counting Spans and for counting SpansEnum (which inherits
from DocIdSetIterator).
Both are produced by a Span Not query:
{code}
private int spanCount(String include, String exclude, int pre, int post)
throws IOException {
SpanTermQuery iq = new SpanTermQuery(new Term(field, include));
SpanTermQuery eq = new SpanTermQuery(new Term(field, exclude));
SpanNotQuery snq = new SpanNotQuery(iq, eq, pre, post);
Spans spans = getSpansFromQuery(snq);
int i = 0;
while (spans.next()){
i++;
}
return i;
}
private int spansEnumCount(String include, String exclude, int pre, int post)
throws IOException {
SpansEnumTermQuery iq = new SpansEnumTermQuery(new Term(field, include));
SpansEnumTermQuery eq = new SpansEnumTermQuery(new Term(field, exclude));
SpansEnumNotQuery senq = new SpansEnumNotQuery(iq, eq, pre, post);
SpansEnum spans = getSpansEnumFromQuery(senq);
int i = 0;
if (spans != null) {
while (spans.nextDoc() != SpansEnum.NO_MORE_DOCS){
while (spans.nextStartPosition() != SpansEnum.NO_MORE_POSITIONS) {
i++;
}
}
}
return i;
}
{code}
