By defining stemming rules you can control how Index Manager interprets searches for morphological variations of a word. In simple terms, it allows you to for example search for a singular form on a noun and have the search engine also return files that contain metadata with the plural form.

The Stemming.dat file is a plain text file that can be opened and edited in e.g. Notepad. It contains standard stemming rules that relate to English. Note, however, that the search engine has no way of handling exceptions from the general rule. Hence, you may find that certain words fall outside the scope of the rules configured simply because they have special conjugation patterns.

Information about how to configure stemming can be found in the Stemming.dat file itself. Changing the contents of the stemming file will require you to completely rebuild the index(es) to incorporate the changes.

Usage note: In FotoStation you will have to use the advanced search dialog and enable Use word stemming (located under Search Options) if you want enable stemming search in Index Manager. In FotoWeb, stemming can be enabled site-wide for all users on the Searching page under Site Settings.

Note: After defining stemming rules, it is necessary to restart the Index Manager service and rebuild any existing indexes to incorporate the changes.
