Index Discovery Jobs with Custom NOISE.DAT and/or DEFAULT.ABC

Note: The dtSearch resource file NOISE.DAT will be blank to allow for all text to be indexed. This change affects new indexes and new or existing searches. For reference, the original dtSearch default noise word list is stored in the Controller, Controller Limited, and Worker directories. The name is NOISE.DAT.DEFAULT.

Custom NOISE.DAT and/or DEFAULT.ABC files may be used to index a Discovery Job. Prior to starting the Discovery Job, place one or both of these files in either the Case (Project) directory (all Discovery Jobs for the Case (Project) will use these file(s) for indexing when started) or in the Discovery directory (only the single Discovery Job will use the file(s) when started). Indexing may be created during initial discovery (default setting) or post creation.

The NOISE.DAT file is used to prevent dtSearch from indexing certain noise words. This file may be modified using a text editor application, such as Notepad. The words in the list can contain the wildcard characters * and ? but must begin with a letter.

When you create an index, dtSearch stores a copy of the noise word list in the index. Therefore, changes to the noise word list will only affect indexes created after the changes were made.

The DEFAULT.ABC file determines how dtSearch interprets certain characters in the documents (characters in the ASCII range from 32-127). Other character properties are set to conform to the Unicode Standard and cannot be modified. You can open this file with Notepad or Textpad for editing.
