BITAND

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

Format

FieldText=BITAND{yourInteger}:yourBitFields

yourInteger	An integer. A document returns only if one of yourBitFields contains a value that results in a non-zero value when a bit-wise AND operation is performed between this value and the specified integer.
yourBitFields	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 non-zero value when a bit-wise AND operation is performed between it and yourInteger. Separate multiple fields 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 IDOL Content Component contain. Only documents whose BitField values result in a non-zero value when they are compared to the binary representation of 128 are returned.

If the BitField, for example, contains the integer value 129, the document returns, while a document whose BitField contains the value 127 does not return.

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.
