Hi everybody.

I'm new here, learning the elasticsearch.
I want to be able to find a full sentence like "live usa" while "usa" is an synonyms of (usa,united states,u s a,united states of america"

if I search for only "usa" or "u s a" etc. It's found all the occurances, but if I search for "live usa" it;s found nothing.

// below my code.

PUT /my_index
{
  "settings": {
    "analysis": {
      "filter": {
        "my_synonym_filter": {
          "type": "synonym",
          "synonyms": [
            "usa,united states,u s a,united states of america"
          ]
        }
      },
      "analyzer": {
        "my_synonyms": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "my_synonym_filter"
          ]
        }
      }
    }
  },
   "mappings": {
    "table1": { 
      "properties": { 
        "text":    { "type": "text"  ,"analyzer": "my_synonyms" }
      }
    }
  }
}

POST /my_index/table1/_bulk
{ "index": { "_id":1}}
{"text":"I live in the usa"}
{ "index": { "_id":2}}
{"text":"the united states of america are pluralzse"}
{ "index": { "_id":3}}
{"text":"I want to visit canade"}
{ "index": { "_id":4}}
{"text":"can you go to the u s a?"}

GET /my_index/table1/_search
{
  "query": {
    "match_phrase": {
      "text": {
        "query": "usa",
        "analyzer": "my_synonyms"
      }
    }
  }
}

thanks in advance!

I suspect your problem with finding a phrase "live usa" is not because of synonyms. It is because there is no such a phrase in your documents. Try to search for the phrase "live in the usa" and see if you can find any documents.
