## Class BigIntegerPoint

    IndexableField

      public class BigIntegerPoint
      extends Field

  An indexed 128-bit `BigInteger` field.

  Finding all documents within an N-dimensional shape or range at search time is efficient. Multiple values for the same field in one document is allowed.

  This field defines static factory methods for creating common queries:

  - `newExactQuery(String, BigInteger)` for matching an exact 1D point.
  - `newSetQuery(String, BigInteger...)` for matching a set of 1D values.
  - `newRangeQuery(String, BigInteger, BigInteger)` for matching a 1D range.
  - `newRangeQuery(String, BigInteger[], BigInteger[])` for matching points/ranges in n-dimensional space.
  See Also:
    `PointValues`

      Create a query for matching an exact big integer value.

      This is for simple one-dimension points, for multidimensional points use `newRangeQuery(String, BigInteger[], BigInteger[])` instead.

      Parameters:
        `field` - field name. must not be `null`.
        `value` - exact value. must not be `null`.
      Returns:
        a query matching documents with this exact value
      Throws:
        `IllegalArgumentException` - if `field` is null or `value` is null.

    - #### newRangeQuery

          public static Query newRangeQuery(String field,

                                            BigInteger upperValue)

      Create a range query for big integer values.

      This is for simple one-dimension ranges, for multidimensional ranges use `newRangeQuery(String, BigInteger[], BigInteger[])` instead.

      You can have half-open ranges (which are in fact </≤ or >/≥ queries) by setting `lowerValue = BigIntegerPoint.MIN_VALUE` or `upperValue = BigIntegerPoint.MAX_VALUE`.

      Ranges are inclusive. For exclusive ranges, pass `lowerValue.add(BigInteger.ONE)` or `upperValue.subtract(BigInteger.ONE)`

      Parameters:
        `field` - field name. must not be `null`.
        `lowerValue` - lower portion of the range (inclusive). must not be `null`.
        `upperValue` - upper portion of the range (inclusive). must not be `null`.
      Returns:
        a query matching documents within this range.
      Throws:
        `IllegalArgumentException` - if `field` is null, `lowerValue` is null, or `upperValue` is null.

    - #### newRangeQuery

          public static Query newRangeQuery(String field,
                                            BigInteger[] lowerValue,
                                            BigInteger[] upperValue)

      Create a range query for n-dimensional big integer values.

      You can have half-open ranges (which are in fact </≤ or >/≥ queries) by setting `lowerValue[i] = BigIntegerPoint.MIN_VALUE` or `upperValue[i] = BigIntegerPoint.MAX_VALUE`.

      Ranges are inclusive. For exclusive ranges, pass `lowerValue[i].add(BigInteger.ONE)` or `upperValue[i].subtract(BigInteger.ONE)`

      Parameters:
        `field` - field name. must not be `null`.
        `lowerValue` - lower portion of the range (inclusive). must not be `null`.
        `upperValue` - upper portion of the range (inclusive). must not be `null`.
      Returns:
        a query matching documents within this range.
      Throws:
        `IllegalArgumentException` - if `field` is null, if `lowerValue` is null, if `upperValue` is null, or if `lowerValue.length != upperValue.length`

    - #### newSetQuery

          public static Query newSetQuery(String field,
                                          BigInteger... values)

      Create a query matching any of the specified 1D values. This is the points equivalent of `TermsQuery`.
      Parameters:
        `field` - field name. must not be `null`.
