Elastic search: exact match query on string array - elasticsearch

Question

Given this document:
{"name": "Perfect Sunny-Side Up Eggs","ingredientList": ["canola oil","eggs"]}
How can I build a query in elastic search to return exact matches on a string array given query term "oil eggs", so far this it what I have, but it returns other irrelevant documents:
POST /recipes/recipe/_search
{
"query": {
"match": {
"ingredientList": {
"query": [
"oil",
"eggs"
],
"operator": "and"
}
}
}
}
for instance, this document is returned but it doesn't contain "oil". Results should only contain "oil" and "eggs":
{"name": "Quick Baked French Toast","ingredientList": ["butter","cinnamon raisin bread","eggs"]}

Answer 1

Your query will look like this:
{
"query": {
"bool": {
"must": [
{
"term": {
"ingredientList": "oil"
}
},
{
"term": {
"ingredientList": "eggs"
}
}
]
}
}
}
Gives me the results:
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
"_index" : "ingredients",
"_type" : "recipe",
"_id" : "AVeprXFrNutW6yNguPqp",
"_score" : 1.0,
"_source" : {
"name" : "Perfect Sunny-Side Up Eggs",
"ingredientList" : [ "canola oil", "eggs" ]
}
} ]
}
}

Answer 2

Elastic dont have API to exact match array. But same can be achieved using two methods:
Using multiple must blocks (not preferred)
Using terms set query and script
"query": {
"bool": {
"must": [
{
"terms_set": {
"ingredientList": {
"terms": ingredients,
"minimum_should_match_script": {
"source": "Math.min(params.num_terms, {})".format(len(ingredients))
}
}
}
},
{
"script": {
"script": {
"inline": "doc['ingredientList'].length == params.list_length",
"lang": "painless",
"params": {
"list_length": len(ingredients)
}
}
}
}
]
}
}
