Applies to: FAST Search Server 2010
Managed properties in Microsoft FAST Search Server 2010 for SharePoint can be one of the following data types:
Handling of items with invalid values
UTF-8 encoded text string.
Text from crawled properties mapped to managed properties in other character encoding is converted to UTF-8 as part of input processing. The text string can consist of words with lengths from 1 byte to a maximum of 1000 byte of length.
Words longer than 1000 bytes are truncated.
If there are more than 4294967296 words in one full text index field, or across all managed properties, the item will not be indexed, and a warning will be logged by the indexer producer.
By default, the maximum size of an input document is 20MB. Any documents longer than this are truncated to this length.
Illegal XML characters: Item indexed, illegal XML characters filtered out during item processing.
Illegal UTF-8 characters: Item not indexed, and warning logged during processing.
Signed 64 bit integer.
Larger number than can fit in 64 bits: Item is not indexed, and warning logged to the index producer logs.
Illegal characters (non-numeric): Item not indexed, and warning logged to the index producer logs.
Integers are converted to Boolean values during processing (0 is treated as false, while any other positive or negative number is treated as true).
Other illegal characters (not true or false): Item not indexed, and warning logged to the indexer producer logs.
Double-precision 64-bit floating point, as specified in IEEE-754.
Larger than can fit in 64 bits double format: Item not indexed, and warning logged to the indexer producer logs.
