The Content Acquisition System provides a list of capabilities that describe whether a data source or manipulator supports an optional set of CAS features. For example, if a data source or manipulator has the Supports Incrementals capability, then it can run in an incremental crawl.
You get the capabilities for a data source or manipulator by running the
listModules task or the
getModuleSpec task of
cas-cmd.
The list of CAS capabilities available to a data source or manipulator includes the following:
Binary Content Accessible via FileSystem - Indicates that the data source supports local caching for files accessible from a file system. This capability does not apply to manipulators.
Data Source Filter - Indicates that the data source supports filter configuration. This capability does not apply to manipulators.
Has Binary Content - Indicates that the data source supports document conversion. This capability does not apply to manipulators.
Expand Archives - indicates that the data source supports archive expansion as part of a crawl. This capability does not apply to manipulators.
Supports Incrementals - Indicates that the manipulator can run as part of an incremental crawl. This capability does not apply to data sources.
