Hey all, I have this use case where I am indexing names of people (for a phonebook kind of app) and I try to autocomplete based on name and number, I am doing edge anagrams and it's working fine, the number autocomplete is also working fine. The result order for the name autocomplete however needs tweaking a bit. Say we have a name like: Barack Hussein Obama I want a person typing "Barack O" to see that as the first result. What is happening now is that some of the top results could be - Obama Barack Etc.. - SomeOtherFirstName Barack Obama SomeOther last name I want to boost results that have the entered tokens in the very first position and the very last position more i.e. First and last names matching should have priority, is this possible? Thanks in advance. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Guys, any ideas?

I think I would tackle this at the indexing level. Include another field (or multi-field) which extracts just the first and last word. You could do this with the Pattern Tokenizer, and use a regex like: ^(\w+?)\b.\*\b(\w+?)$ That will extract the first and last word and ignore everything in between. Now you have a field that contains just two tokens, and you can combine your previous query with another query that searches this new field (using a Boolean). If you boost the new field you'll naturally sort "first/last" matches to the top.

I think it would be nice if you could extract the first and last name and the concatenate them into a single string that is stored in one field (firstNameLastName). Then at query time you query against that field alongside other fields (like fullName). Assign a higher importance to the firstNameLastName field and a lower importance to the fullName field. This can be done with the boolean query > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

You might need a custom analyzer (Token Filter) that automates the extraction of the first and last names and then combines them into one string within ES. So the following original tokens will change as follows after being processed by the Token Filter George Walker Bush =\> George Bush George Herbert Walker Bush =\> George Bush Barack Hussein Obama =\> Barack Obama Assuming there are no titles, salutations and suffixes in the name. You can just split the original string into an array using the space character as a delimiter and then concatenate the first and last elements of the array into a string.
