Complex search

Elastic Stack Elasticsearch
1

Hi,
I'm looking to create a search behaviour like Amazon does.

I have an index with 3 Fields : Title, Description and Category.

I want to search in the fields title and descriptions for the word "car"
and I would like to get scored result like this :

car --> score : 1 in category vehicles
autocar --> score : 0,5 in category vehicles where the part "car" should
highlighted ex : autocar
carradio --> core : 0,5 in category vehicles where the part "car" should
highlighted ex : carradio

and that if the word is found in the title field, the score should be
higher as if the word would only be found in the description field.

Is anybody out there who could help me on this topic or at least point me
to the right direction where I should look for ?

Thanks,
Serge

Take a look at highlighting
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-highlighting.html for
highlighting the relevant parts of matches and at multifield
http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/multi-match-query.html#_boosting_individual_fieldssearch
queries with boosting on individual fields.
