Guidelines for catalog Readme files
Another recommended practice is to place a separate Readme file in the folder with the
index. Use this Readme file to describe the index, such as the following information:
The kind of documents indexed.
The search options supported.
The person to contact or a phone number to call with questions.
A list of numbers or words that are excluded from the index.
A list of the folders containing documents included in a LAN-based index, or a list of the
documents included in a disk-based index. You might also include a brief description of
the contents of each folder or document.
A list of the values for each document if you assign Document Info field values.
If a catalog has an especially large number of documents, consider including a table that
shows the values assigned to each document. The table can be part of your Readme file or
a separate document. While you are developing the index, you can use the table to
maintain consistency.
