Summary of Style Files


The configuration options available in style files allow you to modify these characteristics of a document collection:

The style files can be categorized as follows:

Standard Style Files

A listing of the standard style files is provided below.

Editable Standard Style Files

Not all style files should be edited-only those identified below.

File
Description
Purpose
style.sfl
This is the standard field list file. It specifies field definitions for the Verity standard fields. By default, these fields are populated by the universal filter.
Documents table schema definition
style.ufl
This is the user-defined field list file where you can specify custom field definitions.
Documents table schema definition
style.lex
This is the lexical definition file. It is where you define non-alphanumeric characters to be interpreted as searchable characters.
Word index tuning
style.stp
This is the word exclusion, or stop word list file. It contains a list of words that will be excluded from a collection's full-word index.
Word index tuning
style.go
This is the word inclusion list file. It contains a list of the specific words that will be included in a collection's full-word index. Only the words listed will appear in the index.
Word index tuning
style.fxs
This is the feature extraction word-exclusion file. In this file, you can specify the words that are not to be considered when scoring sentences for best sentence summaries, and are also not to be taken into account when forming clusters.
Feature extraction tuning
style.prm
This is the parameter file, where you can specify what you want included in or excluded from the collection indexes. Additional data in collection indexes support some search features, like clustering, query-by-example, and the SOUNDEX operator. The style.prm file can be used to specify case-insensitive word indexes, supporting case-insensitive searching.
Collection tuning and indexing behaviors
style.plc
This is the policy file in which you specify the indexing mode to be used for a collection.
Indexing performance
style.tde
This is the field extraction rule file in which you specify the rules to be used when extracting fields with the mkvdk option,
-extract.

Field extraction rules
style.dft
This is the document format file, that overrides the default virtual document definition. This file defines the content of the document, which determines how the document will be filtered and viewed.
Document format and filter specification
style.uni
This is the universal filter file that tells the universal filter which helper filters to load in what order for every possible document type.
Universal filter configuration
style.zon
This is the zone file. It is used to define how SGML and HTML documents are filtered.
Zone filter configuration

Gateway-Related Style Files

The gateway-related style files affect the behavior of a particular gateway type, such as the HTTP gateway or the File System gateway.

File
Description
vgw*.cfg
The gateway type configuration file that specifies which repositories will be indexed and configuration options specific to the gateway type. The name of the gateway type configuration file depends on the gateway type. For example, the configuration file for the HTTP gateway is called vgwhttp.cfg.

This file is used for repository access.

vgw*.gfl
The gateway field definition file. This file is defined by Verity for each gateway type. The fields defined in this file are required for proper gateway functioning. The name of the gateway field definition file depends on the gateway type. For example, the gateway field definition file for the HTTP gateway is called vgwhttp.gfl.

This file contains the documents table schema definition.

vgw*.prm
