Auto-complete configuration allows you to set the proportion of documents in the index where a term should appear to be suggested in the auto-complete. The higher this proportion, the less terms are going to be suggested.
In order to configure auto-complete, you have to be the search administrator, and access to the UI.
Now you can set the value to something between 0 and 1, then click the “confirm” button.
Core reload required
Keep in mind that Datafari takes the changes into account only after you have pushed the configuration through the zookeeper admin page, and restarted your Datafari.
