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:

IDOL 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).

NOTE:

If you change this setting after you have indexed content into IDOL Server, 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.
