Defining File Types for Indexing

M-Files Server tries to index the contents of the most general file types when a new file version is checked in to M-Files Server. Indexing enables users to search documents and objects from M-Files using the words that can be found in the file content. This topic lists the files whose contents are indexed by default and tells how to add file types to be indexed and how to exclude file types from indexing.

Note: Metadata is always indexed regardless of whether the file extension is in the list of file types to be indexed or in the blacklist of file types not to be indexed.

The following table lists the extensions of files whose contents are indexed by default when dtSearch or Micro Focus IDOL search engine is in use.

Using Blacklist in Indexing

If you do not want to use the default list of file types to be indexed, you can use the built-in blacklist instead. The blacklist contains a predefined set of file extensions specifying the file types that are not indexed.

Complete the following steps to set the built-in blacklist to be used in indexing:

  1. In M-Files Admin, go to the Advanced Vault Settings section.
    1. Open M-Files Admin.
    2. In the left-side tree view, expand a connection to M-Files Server.
    3. In the left-side tree view, expand Document Vaults, and then expand a vault.
    4. In the left-side tree view, select Configurations, and then in the gray navigation area, select Advanced Vault Settings.
    5. Open the Configuration tab.
      Result:The advanced vault settings are shown.
  2. Expand Search > Full-Text Search.
  3. Set Use File Extension Blacklist Instead of Whitelist in Indexing to Yes.
  4. Click Save.

Defining Additional File Types for Indexing

In addition to either the list of file types to be indexed or the list of file types not to be indexed, you can define other file types to be indexed. Also, you can define some file types you do not want to be included in indexing. For example, you have the list of file types to be indexed, but you would like to exclude one of the file types from indexing. To exclude the file contents from indexing, you must define the file extension according to the following instructions.

To define file types to be indexed or not to be indexed:

  1. In M-Files Admin, go to the Advanced Vault Settings section.
    1. Open M-Files Admin.
    2. In the left-side tree view, expand a connection to M-Files Server.
    3. In the left-side tree view, expand Document Vaults, and then expand a vault.
    4. In the left-side tree view, select Configurations, and then in the gray navigation area, select Advanced Vault Settings.
    5. Open the Configuration tab.
      Result:The advanced vault settings are shown.
  2. Expand Search > Full-Text Search > Files to Index or Files Not to Index.
  3. Click Add Extension.
  4. In the Extension field, enter the file extension, for instance dwg.
  5. Repeat the steps 3 and 4 for each file extension.
  6. Click Save to save your configuration.
