I verified i can do a search via sample search query below. How do i search for items , say that falls in category electronics .

GET _search
{
   "query" : {
      "match_all" : {}
   }
}

sample data

{
  "_index"  :  "my_index",
  "_id"     :  "123abc", 
  "_score"  :  1,
  "_source" :  {
                  "_id"      : "123abc",
                  "vector"   : [ 1, 2, 3 ....],
                  "category" : ["electronics", "stationary" ]

GET /my_index/_search
{
  "query": {
    "term": {
      "category": "electronics"
    }
  }
}

If you want to set an or condition, you can use the should syntax. If any of the conditions in the should are met, the match will succeed.

GET /my_index/_search
{
  "query": {
    "bool": {
      "should": [
        { "term": { "category": "electronics" } },
        { "term": { "category": "stationary" } }
      ],
      "minimum_should_match": 1
    }
  }
}
