Constructor Detail

### DistanceQuery

    public DistanceQuery(List<SrndQuery> queries,
                         boolean infix,
                         int opDistance,
                         String opName,
                         boolean ordered)

Method Detail

### getOpDistance

    public int getOpDistance()

### subQueriesOrdered

    public boolean subQueriesOrdered()

### distanceSubQueryNotAllowed

    public String distanceSubQueryNotAllowed()

  Description copied from interface: `DistanceSubQuery`
  When distanceSubQueryNotAllowed() returns non null, the reason why the subquery is not allowed as a distance subquery is returned.
  When distanceSubQueryNotAllowed() returns null addSpanNearQueries() can be used in the creation of the span near clause for the subquery.

  Specified by:
    `distanceSubQueryNotAllowed` in interface `DistanceSubQuery`

### addSpanQueries

    public void addSpanQueries(SpanNearClauseFactory sncf)
                        throws IOException

  Specified by:
    `addSpanQueries` in interface `DistanceSubQuery`
  Throws:
    `IOException`

### getSpanNearQuery

    public Query getSpanNearQuery(IndexReader reader,
                                  String fieldName,
                                  float boost,
                                  BasicQueryFactory qf)
                           throws IOException

  Throws:
    `IOException`

### makeLuceneQueryFieldNoBoost

    public Query makeLuceneQueryFieldNoBoost(String fieldName,
                                             BasicQueryFactory qf)

  Specified by:
    `makeLuceneQueryFieldNoBoost` in class `SrndQuery`
