  Q256986 Description of the Microsoft Windows Registry

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

The following is an example on how to remove all word breakers except for the
Neutral word breaker

1. Run Regedt32.exe.

2. Select:

  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ContentIndex\Language

3. Select the Language key and Save it to a backup file.

4. Double-click on the InstalledLangs value and remove all lines except for the
  one showing "Neutral". Click OK.

5. Delete all keys except Neutral below Language.

6. Stop and then restart the index service.

7. Rebuild the catalog by doing a full build.

There are some differences that should be noted when using only the Neutral word
breaker:

- In all languages, "advanced" normalization acts differently:

   - Dates: 9/9/99 and 9-9-1999 will not match

   - Numbers: 1,000 and 1000 will not match

   - Hyphens: database and data-base will not match

- In German compound decomposition will not work.

- In other European languages lose clitic stripping is lost, which may reduce
  the chances of matching.

- Word stemming will no longer work. Word stemming is where a query on "flew**"
  returns documents matching flew, fly, flown, and so forth.
