Our priority is Name Surname and Phone Number while we are creating a New Individual Entry However when the same info is written, the system doesn't give a warning, which causes to create new accounts with the existed info beforehand. to solve this problem i have examined this essay below but i haven't got the desired results. https://civicrm.org/blog/spidersilk/understanding-civicrm-dedupe-rules
What i want is that the system shall not let me to create New Individual Entry if there is this phone number in somebody's profile already.
Could you please launch a "Matching Rule for Individual Contacts" to this.
