Indexing input data

Indexing parameters include information that allow the PDF indexer to identify key items in the print data stream, tag these items, and create index elements pointing to the tagged items.

Content Manager OnDemand uses the tag and index data for efficient, structured search and retrieval. You specify the index information that allows the PDF indexer to segment the data stream into individual items, known as groups. A group is a collection of one or more pages, such as a bank statement, insurance policy, phone bill, or other logical segment of a report. The PDF indexer creates indexes for each group when the value of an index changes (for example, account number).

A tag is made up of an attribute name, for example, Customer Name, and an attribute value, for example, Earl Hawkins. Tags also include information that tell the PDF indexer where to locate the attribute value on a page. For example, a tag used to collect customer name index values provides the PDF indexer with the starting and ending position on the page where the customer name index values appear. The PDF indexer generates index data and stores it in a generic index file.
