depth indexing
n.
A process of providing access to detailed information contained within documents.
Notes
Depth indexing is distinguished from general indexing, which provides access to the broad subjects treated by a document as a whole. For example, general indexing may create entries for the author, recipient, and possibly a few subjects of a letter; depth indexing might provide access to every name mentioned in the letter. The level of detail that is indexed is described as the specificity of indexing.
