Introduction

The following functions are used in the Generate stage of filtering. Generation functions can generate information that goes into a resource description. In general, they either extract information from the body of the resource itself or copy information from the resource’s metadata.

extract-full-text

The extract-full-text function extracts the complete text of the resource and adds it to the resource description.

The extract-full-text function should be used with caution, because it can significantly increase the size of the resource description, thus causing database bloat and overall negative impact on network bandwidth.

Parameters

The parameters used with the extract-full-text function and their description are:

truncate

The maximum number of characters to extract from the resource.

dst

Name of the schema item that will receive the full text.

Example

Generate fn=extract-full-text
