Query suggestion for a search engine

Elastic Stack Elasticsearch
1

Hi,
I am currently working on a web search engine just like Google for my web site. I have crawled my website pages and indexed data in Elasticsearch. the indexed documents have such fields:

    string Id 
    string Url
    string Title
    string Body 
    string MetaKeywords
    string MetaDescription 
    List<string> H1 
    List<string> H2
    List<string> H3 
    List<string> H4 
    List<string> H5 
    List<string> H6
    int Depth   // the page depth in the website: usually, if this number is less, the page is more relevant

I was looking for a query that gets an array of words as input and returns the most related pages.
I will be very grateful if you use techniques that will improve the results like boosting, or what ever you know.
Also, I slightly prefer the words to be "and" with each other. for example if the input was ["foo", "bar", "baz"] the returned results should contain all these words and not just one of them (or at least the result should have most of the words). I suppose this behavior is more similar to the current search engines to prevent showing unrelated pages.
I know this question is too general and does not have a single correct answer but I just wanted to learn options and features that I can use.

Thanks a lot.

Hi @jahedi ,

Have you also considered using semantic search through vector search?

Hi @Alex_Salgado-Elastic
Actually no! I am currently using free and basic license of the Elasticsearch

Vector search is available with the basic tier :blush:
