Mixing conditional operators with facets in Elasticsearch - ruby-on-rails

Question

I am trying to match a search query against two fields, as well as filter by facets if selected from dropdowns on the page.
When the user enters keywords it should match if found in two database fields: Title and Description. The dropdowns filter by a status, and a type.
Here is my Tire search configuration:
def self.search(params)
tire.search(load: true, page: params[:page], per_page: 25) do
query do
boolean do
should { string "title:#{params[:query]}", default_operator: "OR" } if params[:query].present?
should { string "description:#{params[:query]}", default_operator: "OR" } if params[:query].present?
must { term :status_id, params[:status_id] } if params[:status_id].present?
must { term :type_id, params[:type_id] } if params[:type_id].present?
end
end
sort { by :updated_at, "desc" } if params[:query].blank?
facet "status" do
terms :status_id
end
facet "type" do
terms :type_id
end
end
end
Indexing settings:
settings :analysis => {
:filter => {
:my_ngram => {
"type" => "nGram",
"max_gram" => 10,
"min_gram" => 3}
},
:analyzer => {
:my_analyzer => {
"type" => "custom",
"tokenizer" => "lowercase",
"filter" => ["my_ngram"]
}
}
} do
mapping do
indexes :title, boost: 10, analyzer: 'my_analyzer'
indexes :description, boost: 5, analyzer: 'my_analyzer'
indexes :status_id, :type => 'integer'
indexes :type_id, :type => 'integer'
end
end
I originally only had the title and description fields, which was working fine. I am now trying to add the ability to filter by status and type.
What is the proper way to configure this? If status is selected, it should only return records with that status. The same follows for type, and if both are selected.
Any help is appreciated.
It's not that errors occur, but the results no longer filter at all by either keywords or facets:
curl -X GET 'http://localhost:9200/projects/project/_search?load=true&size=25&pretty' -d '{"query":{"bool":{"should":[{"query_string":{"query":"title:test","default_operator":"OR"}},{"query_string":{"query":"description:test","default_operator":"OR"}}],"must":[{"term":{"status_id":{"term":"1"}}},{"term":{"type_id":{"term":"1"}}}]}},"facets":{"status":{"terms":{"field":"status_id","size":10,"all_terms":false}},"type":{"terms":{"field":"type_id","size":10,"all_terms":false}}},"size":25}'

If you could create the equivalent of this I think you would get the desired results. (Please excuse the lack of quotes on the JSON keys!)
{
query: {
multi_match: {
query: "test",
fields: ["title", "description"]
}
},
filter: {
and: [
{
term: { status_id: 123 }
},
{
term: { type_id: 456 }
}
]
},
facets: {
type: {
terms: {
field: "type_id",
size: 10
}
},
status: {
terms: {
field: "status_id",
size: 10
}
}
}
}
Update
I don't know tire but will try to write something!
def self.search(params)
tire.search(load: true, page: params[:page], per_page: 25) do
query do
boolean do
should { match :title params[:query] } if params[:query].present?
should { match :description params[:query] } if params[:query].present?
end
end
sort { by :updated_at, "desc" } if params[:query].blank?
filter :and, { :term => { :status_id => params[:status_id] } } if params[:status_id].present?
{ :term => { :type_id => params[:type_id] } } if params[:type_id].present?
end
end
You will probably have to fix the ruby, but a few things to note. Match queries are the recommended default string search, they are faster than query_string ones (though you have slightly less control). Also
