updateaspell

The admin?op=updateaspell administrative operation lets you rebuild the aspell dictionary for spelling correction from the data corpus without stopping and restarting the MDEX Engine.

The admin?op=updateaspell operation performs the following actions:

Crawls the text search index for all terms
Compiles a text version of the aspell word list
Converts this word list to the binary format required by aspell
Causes the Dgraph to finish processing all existing preceding queries and temporarily stop processing incoming queries
Replaces the previous binary format word list with the updated binary format word list
Reloads the aspell spelling dictionary
Causes the Dgraph to resume processing queries waiting in the queue

The Dgraph applies the updated settings without needing to restart.

Only one admin?op=updateaspell operation can be processed at a time.

The admin?op=updateaspell operation returns output similar to the following in the Dgraph error log:

...
aspell update ran successfully.
...

Note: If you start the Dgraph with the -v flag, the output also contains a line similar to the following:

Time taken for updateaspell, including wait time on any 
previous updateaspell, was 290.378174 ms.
