coordinate indexing造句怎么写

A word, symbol, or number used as a descriptor for retrieval of information from a collection, especially in a coordinate indexing system.

A document should be indexed more generally first by descriptors, such as coordinate indexing, hypernym indexing and proximate indexing; then by free term specially, namely double indexings.

This type of coordinate indexing is said to be manually operated, since the recording of the accession number onto the features card is done by hand.
