Hello. I have an online store built with Ruby on Rails, where I want to index my products' specs/attributes and then provide filtering options to my users. I'm in the process of figuring out how I will build my queries, and I want some help. I'm using the elasticsearch-model gem, with which I can do queries like this: `Product.search(filter: { bool: { filter: [{term: {category_id: 7}}, {range: {price: {gte:51.5, lte: 60}}}]} })` meaning "give me all products from category X that are in the following price range". 1. The query above returns the proper results, but is it the way to go or I can write this in a more idiomatic/correct way? 2. I'm thinking about how should I _build_ compound queries like this in an imperative fashion, based on input that user has given me (through query string params in the URL or something). Should I use the elasticsearch-dsl gem or I can do this by just constructing the hashes my own? 1. I tried to convert that query using the elasticsearch-dsl gem but failed to do so: Thanks in advance! ---
