lucene-SpanNotQuery和SpanOrQuery交迭与全局跨度
1、在匹配结果中排除相互交迭的跨度
SpanNotQuery构造函数的第一个参数表示要包含的跨度对象，第二个参数表示要排除的跨度对象。
1)
SpanNearQuery quick_fox=new SpanNearQuery(newSpanQuery[]{quick,fox},1,true);
dumpSpans查询时输出
the <quick brown fox> jumps overthe lazy dog (0.18461232)
the <quickredfox> jumps over thesleep cat(0.18461232)
2)
SpanNotQuery quick_fox_dog=new SpanNotQuery(quick_fox,dog);
dumpSpans查询时输出
the <quick brown fox> jumps overthe lazy dog (0.18461232)
the <quickredfox> jumps over thesleepcat(0.18461232)
3)只匹配了第一个文档，因为第二个文档包括red
SpanNotQuery no_quick_red_fox=newSpanNotQuery(quick_fox,red);
dumpSpans查询时输出
the <quickredfox> jumps over thesleep cat(0.18461232)
2、SpanOrQuery，在构造函数中对一个SpanQuery对象的集合进行封装
1)
SpanNearQuery qf_near_ld=new SpanNearQuery(newSpanQuery[]{quick_fox,lazy_dog},3,true);
dumpSpans查询时输出
the <quick brown fox jumps over the lazydog> (0.38461232)
2)
SpanNearQuery qf_near_sc=new SpanNearQuery(newSpanQuery[]{quick_fox,sleep_cat},3,true);
dumpSpans查询时输出
the <quickred fox jumps overthesleep cat> (0.38461232)
3）查询这样一些文档，这些文档或者包括"quick fox" near "lazy dog"或者包括"quick fox"near "sleep cat"
dumpSpans查询时输出
the <quick brown fox jumps over the lazydog> (0.38461232)
the <quickred fox jumps overthesleep cat> (0.38461232)
