Reserved index field names

When you configure a crawler, the system automatically creates index fields that are specific to the crawler type. These index field names are reserved by Watson Content Analytics.

For example, if you configure a DB2 crawler or a JDBC database crawler, the system automatically creates an index field for the database name.

In addition to field names that are reserved by crawlers, the following field names are reserved because they are used in the Watson Content Analytics query syntax:

date
docid
link
samegroupas
site
title
url

When you configure index fields for a collection, you cannot specify any of the reserved field names as index field names. The following table shows additional field names that are reserved by the various crawlers.

Table 1. Field names reserved by crawlers
