    Subclasses of Spans in org.apache.lucene.search.spans
    Modifier and Type | Class and Description
    --- | ---
    `class` | `FilterSpans` A `Spans` implementation wrapping another spans instance, allowing to filter spans matches easily by implementing `FilterSpans.accept(org.apache.lucene.search.spans.Spans)`
    `class` | `NearSpansOrdered` A Spans that is formed from the ordered subspans of a SpanNearQuery where the subspans do not overlap and have a maximum slop between them.
    `class` | `NearSpansUnordered` Similar to `NearSpansOrdered`, but for the unordered case.
    `class` | `TermSpans` Expert: Public for extension only.
