Autofill / Prompt for Account name in Web Forms

Hi Francesca,
It can work well if you use the contact's email domain to identify an account or have another key for identifying link a particular contact with an account.
Is it relevant to your situation?

That might work, the request comes from upper management and I'm still thinking through the practicality and/or feasibility of such a system. 
I believe the intent is to reduce misspellings, diverse spellings and potential duplicates.

One possible approach is to take advantage of Elastic that is already installed and has the relevant information. When the customer/prospect submits an external form, the data is saved as is but it will trigger a check against Elastic to find similar entries. In one of our implementations, we used a scheduled task to regular to scan these new records and notify CRM users when a potential match is found.

Interesting approach, I'm just looking for an effective way to search for possible duplicates in LEADS after somebody created a new contact or account. In the case that similar leads where found they should be listed in a special area of the contact/account recordview as links to these records to enable an effective lead conversion for the user.

Do you have any suggestions on the criteria to determine "similar"?

Things can get complicated with people using abbreviations, multi-language terms, with and without accents and umlauts etc..

For Leads one approach we looked at is creating a dashlet on a Contacts with a list of Leads that share email address with that Contact.
I am not sure how else you would define "similar leads"

Yes, the email is one criteria, but when I read ElasticSearch I get some fantasies :-) Would be good to have an idea how to trigger ES when you have the Accountname or First/Lastname of a Contact  and want to search for the "similarities" in Leads.

In general, email address and mobile/cell phone numbers are a great way to detect uniqueness. For similar text, Elastic has a built in fuzzy search - https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-fuzzy-query.html

For abbreviations, you will probably need a different field against the account and index that. Accents should be handled with fuzzy as it just increases the distance but definitely test that first
