BITANDHEX

The BITANDHEX field specifier (case sensitive) allows you find documents with a field whose hexadecimal string value does not result in 0 when a bit-wise AND operation is performed between this value and a specified hexadecimal string.

Format

FieldText=BITANDHEX{yourHexadecimalString}:yourBitFields

yourHexadecimalString	A hexadecimal string. A document returns only if one of yourBitFields contains a value that result in a non-zero value when a bit-wise AND operation is performed between this value and the specified hexadecimal string.
yourBitFields	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 non-zero value when a bit-wise AND operation is performed between it and yourHexadecimalString. Separate multiple fields 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 IDOL Content Component contain. Only documents whose BitField values result in a non-zero value when they are compared to the binary representation of 7F are returned.

If the BitField, for example, contains the hexadecimal value C0, the document returns, while a document whose BitField contains the hexadecimal value 80 does not return.

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.
