Performing an AND query in elastic search - elasticsearch

Question

I have tried looking for another solution to this, but the Bool query in ES seems to not do quite what I am looking for. Or I am just not using it correctly.
In our current implementation of search we are trying to boost performance/reduce memory footprint of each query by changing our query logic. Today, if you search for "The Red Ball" you may get back 5 million documents because ES returns any document that matches "the" OR "red" OR "ball" which means we get back WAAAAAY too many irrelevant documents (mostly because of the "the" term). I would like to change our query to instead use AND so ES would return only documents that match "the" AND "red" AND "ball".
I am using the NEST Client to do this with C# so an example using the client would be best since that seems to be where I cannot figure out what to do. Thanks

Answer 1

You can simply use query string query with AND operator.
{
"query": {
"query_string": {
"default_field": "your_field", <--- remove this if you want to search on all fields
"query": "the red ball",
"default_operator": "AND"
}
}
}
or simply
{
"query": {
"query_string": {
"query": "the AND red AND ball"
}
}
}
I do not know C#, but this is how it might look in nest(everyone,feel free to edit)
client.Search<your_index>(q => q
.Query(qu => qu
.QueryString(qs=>qs
.OnField(x=>your_field).Query("the AND red AND ball")
)
)
);

Answer 2

I found the appropriate query to make using the NEST client:
SearchDescriptor<BackupEntitySearchDocument> desc = new SearchDescriptor<BackupEntitySearchDocument>();
desc.Query(qq => qq.MultiMatch(m => m.OnFields(_searchFields).Query(query).Operator(Operator.And)));
var searchResp = await _client.SearchAsync<BackupEntitySearchDocument>(desc).ConfigureAwait(false);
Where _searchFields is a List<string> containing the fields to match on and query is the term to search for.
