The Oracle Commerce system divides characters in indexed text into three categories:
Alphanumeric characters including ASCII characters as well as non-punctuation characters in ISO-Latin1 and Windows CP1252.
Non-alphanumeric search characters (configured using the search characters feature, as described below).
Other non-alphanumeric characters (this category is the default for all non-alphanumeric characters not explicitly configured to be in group 2).
During data processing, each word in the source text (that is, searchable properties for record search, dimension values for dimension search) is indexed based on the alternatives for handling characters from the three categories, which is described in subsequent topics.
