You can configure HPE IDOL to automatically separate a compound word into root words at both index and query time. For example, the German word for bicycle pump is a single word Fahrradpumpe that can be divided into Fahrrad and Pumpe.
Create a text file. Use the following format:
[UTF8] rollercoaster roller coaster hemidemisemiquaver hemi demi semi quaver
Each line defines the decomposition for one word. The first word on a line is broken into the remaining words on the line.
Store the text file in the
langfiles directory of your HPE IDOL installation.
Open the HPE IDOL Server configuration file in a text editor. For each language that the decomposition file applies to, specify the file name in the
DecompositionFile configuration parameter. For example:
Each of the terms in the output from the decomposition is also stemmed.
