RATIONALE
Duplicates computation on leads is slow when having a lot of leads. We can
simplify the heuristic to keep only relevant terms and use tailored fields
to find duplicates based on email and phone, to speedup the computation while
loosing few duplicates or avoiding false duplicates.
SPECIFICATIONS
We remove
* an ilike on email_normalized (slow and exact matches are what really
matters);
* an ilike based on partner_name and contact_name (as lead is a contact
oriented record, better optimize email and phone / mobile than names that
are weak criterions);
* an ilike on phone_mobile_search, which was searching on both fields
phone and mobile;
Criterions are now
* email domain exact match;
* phone_sanitized exact match;
* same commercial entity;
Main change is that only phone_sanitized is used for exact match. Partial
matching based on phone and mobile number is lost. That should not be an
issue as real duplicates should come with a complete phone or mobile number
and not partial numbers. First found in phone / mobile populates the phone
sanitized field, meaning if we have two different numbers, only one is used
for duplicate finding. This is considered acceptable.
Other main change is the removal of partner name / contact name search. Those
are weak criterions and did not return any explicit result when used internally.
