# DecompositionFile

The name of a file to use to automatically separate a compound word into root words at both indexing and query time. For example, the German word for bicycle pump is a single word fahrradpumpe that can be divided into fahrrad and pumpe.

The file must have the following format:

    [UTF8]
    rollercoaster roller coaster
    hemidemisemiquaver hemi demi semi quaver

Each line of the file defines the decomposition for one word. The first word on a line is broken down into the remaining words on the line.

NOTE: The Content component also stems each of the terms that the decomposition produces.

You must store the decomposition file in the LanguageDirectory.

NOTE: If you specify a full path to the Stoplist, you must also use a full path in the `DecompositionFile` and StemmingFile parameters. If you do not specify a path to the Stoplist, you must use only the file name in the `DecompositionFile` and StemmingFile parameters (that is, you must place these files in the LanguageDirectory).

Type: | String
Default: |
Required: | No
Configuration Section: | LanguageTypes or `MyLanguage`
Example: | `[German] DecompositionFile=german_decomp.txt`
See Also: | DiminishSeparators SoftSeparators

NOTE: If you change this setting after you have indexed content into the Content component, the new setting applies only to new content, and the server logs a warning. To clear the warning and ensure that your change applies to all your content, you must initialize your index and reindex the content.
