Contacts Duplicates Real Time search is an Odoo partner management tool. The app helps to prevent the appearance of contacts' duplicates or to expose them. The tool can detect that the contact has a duplicate when you create or observe a record, as the app searches for similarities in real time. 

Flexibly set the criteria to find duplicates, and strictly forbid saving the same contact or warning about the existence of a similar one. As duplicate criteria use any stored field of the following types: char, text, many2one, selection, date and datetime, integer, and float. 

Optionally choose to search for duplicates among all contacts or only among companies and stand-alone individuals (without company).

If you also want to find duplicates among opportunities, then consider the app CRM Duplicates Real Time search, which searches for both contacts and opportunities duplicates.

The multi-company mode is supported and the settings are applied to each company separately.

The tool lets you both strictly avoid duplicates and/or just warn of those according to the set rules. A rule is a field by which an item is considered as a copy. For example, an email or a name. Use rigid criteria to fully exclude duplicate creation. Use soft criteria to only notify Odoo users of possible duplicates.  

For all fields, a duplicate should have absolutely the same value. For example, '123' equals '123', but '123' is not equal '1234'. Only for the case of soft search by char fields, the operator is 'ilike'. Thus, 'agro' is considered to be a potential duplicate of 'Agrolait' (but Agrolait is not considered a duplicate of 'agro').

You can set the soft and/or rigid criteria in General settings > Contacts Duplicates. If you choose one and the same field as both rigid and soft criteria, then the rigid criteria will dominate and you will not be able to save the contact with the same value in the field.

After setting soft criteria in the contacts list you will see a mark 'N Potential duplicates' and the button 'N Duplicates' on the contact's card.

After setting rigid criteria, the tool will not let to save a contact with the same value in chosen rigid fields. If you try to save such a partner, a pop-up warning appears. The warning shows the name of a duplicate, its unique ID, and matching fields. That allows you to find the contact easily, or to change the value in the matching fields of the currently created one in order to save a new partner.

See the contacts duplicates from the list view and kanban view. In the list view click on the three dots and then tick 'Duplicates count' to see the column with the number of duplicates to each contact.

You can also filter contacts by potential duplicates, for that click on the 'Filters' above the contacts view and choose 'Potential Duplicates'.

Optionally, you can turn off the calculation of the number of soft duplicates when opening a kanban, tree, or form view. It is particularly useful when you need to speed up the views loading since the app will not calculate potential duplicates for each shown record. The search filter is not influenced by the setting.

To turn off the soft duplicates count in kanban and tree view:

1. Go to General Settings and scroll down to the section 'Contacts Duplicates'

2. Tick the option 'Do not show soft duplicates count (tree and kanban view)'

3. Click 'Save' in the top left corner.

To turn off the soft duplicates count in form view:

1. Go to Settings and scroll down to the section 'Contacts Duplicates'

2. Tick the option 'Do not show soft duplicates count (form view button)'

3. Click 'Save' in the top left corner.

Based on duplicates found you can merge those based on Odoo standard partner merging tools. To that end:

1. Click on the line 'N Potential duplicates' or on the button 'N Duplicates', where N is the number of found duplicates, in the contact's card to see its duplicates and similar fields

2. Choose duplicate records

3. Choose the destination contact

4. Click on a contact to open its card and see details before merging

5. Click 'Add a line' to add one more contact for merging manually

6. Click 'Merge'.

The app searches for the contacts' duplicates in real-time. Every time from any interface view: kanban, list, map, as you create or open a contact, the system searches for matches of the chosen fields among all available contacts. Although the tool is optimized to make searches as efficient as Odoo ORM allows it, with a growing number of documents, a search might become slower as all shown records are checked for duplicates among all existing records.

For example, when you open kanban view with 1000 contacts, the tool makes searches by your criteria among all of them. It may result in slowdowns of the following operations:

1. Opening kanban and list views of Odoo contacts. To avoid that, you may turn off showing the counter for a corresponding view. 

2. Saving changes after updating partners. To avoid that, assign only soft parameters and neglect rigid ones.
