Algolia搜索，其中索引中的字段等于字符串

Question

I'm using Algolia on a Rails application for search:

index = Algolia::Index.new("Search_production")
results = index.search('heroku')

I have an attribute in that index, called type , that's a string.

I want to search only for records with type service .

Can I apply a filter to the Ruby Algolia search? Something like?

results = index.search(query, { facets: '*', facetFilter: ['type:Service' ]})

Answer 1

Yes, using faceting & facetFilters is the way to go to implemented what you're describing, aka "Faceted search"! Don't forget to configure your attributesForFaceting setting in your index settings.

PS: you don't need facets: '*' here, that's not used for the filtering but just to actually retrieve facet values.
