Fields with a Nonzero Value for Bitwise AND

You can use the following field specifiers (case sensitive) to return documents with fields whose value result in a nonzero value when a bitwise AND operation is carried out against a specified value.

BITAND

The BITAND field specifier (case sensitive) allows you to find documents with a field whose integer value does not result in 0 when a bitwise AND operation is carried out between this value and an integer value that you specify.

FieldText=BITAND{yourInteger}:yourBitFields

where:

yourInteger is an integer. A document returns only if one of yourBitFields contains a value that results in a nonzero value when a bitwise AND operation is carried out between this value and the specified integer.
yourBitFields

is one or more fields. A document returns only if it contains one of these fields, and if this field contains an integer that results in a nonzero value when a bitwise AND operation is carried out between it and yourInteger.

If you want to specify multiple fields, separate them with colons (there must be no space before or after a colon).

Example:

FieldText=BITAND{128}:BitField

The binary representation of the integer value 128 is compared with the binary representations of the integer values that BitField fields in HPE IDOL Server contain. Only documents whose BitField values result in a nonzero value when they are compared to the binary representation of 128 return.

For example, if the BitField of a document contains the integer value 129, it returns, but a document whose BitField contains the value 127 does not return.

The following tables show the field value comparison.

Integer Binary  
128 1000 0000  
129 1000 0001  
  1000 0000 this evaluates to True
Integer Binary  
128 1000 0000  
127 0111 1111  
  0000 0000 this evaluates to False

BITANDHEX

The BITANDHEX field specifier (case sensitive) allows you to find documents with a field whose hexadecimal string value does not result in zero when a bitwise AND operation is carried out between this value and a hexadecimal string that you specify.

FieldText=BITANDHEX{yourHexString}:yourBitFields

where:

yourHexString is a hexadecimal string. A document returns only if one of yourBitFields contains a value that results in a nonzero value when a bitwise AND operation is carried out between this value and the specified hexadecimal string.
yourBitFields

is one or more fields. A document returns only if it contains one of these fields, and if this field contains a hexadecimal string that results in a nonzero value when a bitwise AND operation is carried out between it and yourHexString.

To specify multiple fields, separate them with colons (there must be no space before or after a colon).

Example:

FieldText=BITANDHEX{7F}:BitField

The binary representation of the hexadecimal value 7F is compared with the binary representations of the hexadecimal values that BitField fields in HPE IDOL Server contain. Only documents whose BitField values result in a nonzero value when they are compared to the binary representation of 7F return.

For example, if the BitFieldof a document contains the hexadecimal value C0, it returns, but a document whose BitField contains the hexadecimal value 80 does not return.

The following tables show the field value comparison.

Hex Binary  
7F 0111 1111  
C0 1100 0000  
  0100 0000 this evaluates to True
Hex Binary  
7F 0111 1111  
80 1000 0000  
  0000 0000 this evaluates to False

BITANDOFFHEX

The BITANDOFFHEX field specifier (case sensitive) allows you to find documents with a field whose hexadecimal string value does not result in zero when a bitwise AND operation is carried out between this value and an offset hexadecimal string you specify.

FieldText=BITANDOFFHEX{NN,yourHexString}:yourBitFields

where:

NN is the number of 16-bit chunks by which the value in yourHexString and in yourBitFields is shifted before the bitwise AND operation is carried out (this allows you to store sparse bit masks more efficiently).
yourHexString is a hexadecimal string. A document returns only if one of yourBitFields contains a value that results in a nonzero value when a bitwise AND operation is carried out between this value and the specified hexadecimal string.
yourBitFields

is one or more fields. A document returns only if it contains one of these fields, and if this field contains a hexadecimal string that results in a nonzero value when a bitwise AND operation is carried out between it and yourHexString.

If you want to specify multiple fields, separate them with colons (there must be no space before or after a colon).

Example:

FieldText=BITANDOFFHEX{01,0a001}:BitOffField

The binary representation of the hexadecimal value 01,0a001 is compared with the binary representations of the hexadecimal values that BitOffField fields in HPE IDOL Server contain. Only documents whose BitOffField values result in a nonzero value when they are compared to the binary representation of 01,0a001 (after they have been shifted left by one 16-bit chunk) return.

For example, if the BitOffField contains the value 1,bc01, the document returns, but a document whose BitOffField contains the value 0,5ffeffff does not return.

The following tables show the field value comparison.

nn,hexstring Hex Binary  
01,0a001 A0010000 1010 0000 0000 0001 0000 0000 0000 0000  
1,bc01 BC010000 1011 1100 0000 0001 0000 0000 0000 0000  
    1010 0000 0000 0001 0000 0000 0000 0000 this evaluates to True
nn,hexstring Hex Binary  
01,0a001 A0010000 1010 0000 0000 0001 0000 0000 0000 0000  
0,5ffeffff 5FFEFFFF 0101 1111 1111 1110 1111 1111 1111 1111  
    0000 0000 0000 0000 0000 0000 0000 0000 this evaluates to False
