You can modify or replace the Aspell dictionary file. Use the
admin?op=updateaspell
operation for the dgraph which
causes updates to the Aspell dictionary file.
While the dictionary files automatically generated by Dgidx are generally adequate for most applications (especially when using a reasonable value for the minimum number of word occurrences), additional improvements in application-specific spelling behavior can be achieved through modification or replacement of the automatic dictionary file (Aspell module only).
For example, in applications with a specific set of technical
terminology that requires focused spelling correction, you can replace the
automatic dictionary with a manually-generated list of technical terms combined
with a simple list of common words (such as
/usr/dict/words
on many UNIX systems).
