- - ### Uses of SpanQuery in org.apache.lucene.search.spans

    Subclasses of SpanQuery in org.apache.lucene.search.spans
    Modifier and Type | Class and Description
    --- | ---
    `class` | `FieldMaskingSpanQuery` Wrapper to allow `SpanQuery` objects participate in composite single-field SpanQueries by 'lying' about their search field.
    `class` | `SpanBoostQuery` Counterpart of `BoostQuery` for spans.
    `class` | `SpanContainingQuery` Keep matches that contain another SpanScorer.
    `class` | `SpanFirstQuery` Matches spans near the beginning of a field.
    `class` | `SpanMultiTermQueryWrapper<Q extends MultiTermQuery>` Wraps any `MultiTermQuery` as a `SpanQuery`, so it can be nested within other SpanQuery classes.
    `class` | `SpanNearQuery` Matches spans which are near one another.
    `class` | `SpanNotQuery` Removes matches which overlap with another SpanQuery or which are within x tokens before or y tokens after another SpanQuery.
    `class` | `SpanOrQuery` Matches the union of its clauses.
    `class` | `SpanPositionCheckQuery` Base class for filtering a SpanQuery based on the position of a match.
    `class` | `SpanPositionRangeQuery` Checks to see if the `SpanPositionCheckQuery.getMatch()` lies between a start and end position See `SpanFirstQuery` for a derivation that is optimized for the case where start position is 0.
    `class` | `SpanTermQuery` Matches spans containing a term.
    `class` | `SpanWithinQuery` Keep matches that are contained within another Spans.
