The list of MIME types that Sybase Search can index is in the MimeTypeMap.xml configuration file.
A MIME type might have several extensions, each of which may or may not be indexable. The list of MIME types allows Sybase Search to index only those document types that may contain valid text data. By default, common formats such as plain text and HTML are indexable, while executable MIME types are not.
You can add custom MIME types and the appropriate text filter in DocumentFilters.xml. See “Implementing document filters for unsupported files”.
