Question:

Plauti Deduplicate doesn't work anymore. For example, Deduplicate Live does not show any results on a record, Deduplicate Job gives no results, and when I search for a record in the Salesforce search bar, nothing shows up.

Answer:

This is usually related to Salesforce's Einstein Search feature. You can confirm that your problem is related to this by going to Salesforce Setup > Einstein > Einstein Search > Search Manager > Analytics. If the Storage Size there states '0B', or if you get errors when clicking any of the Index Management items at left, this is indeed the case.

There is a workaround that will partially solve this: add the Objects you use most often in PD to a custom query configuration in the Einstein Search settings. There is a maximum of 5 Objects that can be added per configuration. 

Note that it will take a while before Plauti Deduplicate is working again for the added Objects, generally between 30 minutes to a couple of hours.

Another workaround could be to disable a few Einstein Search settings, but this does not always have the desired effect.

Both workarounds are explained below.

Workaround 1:

Add Objects to always search to custom configurations (available for max 5 Objects).

1. In the Salesforce Setup, go to Einstein > Einstein Search > Search Manager > Query Configurations (Manage Custom Configurations).
2. Click the Configuration you want to update, or create a new one.
3. In the Object column, next to Always Search, click the " + " or Edit icon.
4. The "Select Objects to Always Search" window opens.
5. Move the five Objects you use most often in Duplicate Check to the Selected Objects column at the right.
6. Click Save.
7. Repeat for all configurations that apply to profiles that make use of Plauti Deduplicate.
8. Wait a while (30 minutes to a couple of hours) until PD is working again for the added Objects.

 Workaround 2:

Disable Einstein Search settings (is not always effective).

1. In the Salesforce Setup, go to Einstein > Einstein Search > Settings
   
2. Untick the settings Personalization, Actionable Instant Results, and Natural Language Search.
3. Click Save.
