SquidStd.Search.Elasticsearch

Elasticsearch provider for SquidStd.Search. Indexes IIndexableEntity documents and exposes a constrained LINQ IQueryable<T> translated to the Elasticsearch query DSL; the native ElasticsearchClient is registered for advanced queries.

Install

dotnet add package SquidStd.Search.Elasticsearch

Usage

using DryIoc;
using SquidStd.Search.Abstractions.Interfaces;
using SquidStd.Search.Elasticsearch.Data.Config;
using SquidStd.Search.Elasticsearch.Extensions;
using SquidStd.Search.Elasticsearch.Linq;

container.AddElasticsearch(new ElasticsearchOptions { Uri = new Uri("http://localhost:9200") });

var search = container.Resolve<ISearchService>();
await search.IndexAsync(new Order("1", "open", 150), refresh: true);

var open = await search.Query<Order>()
    .Where(o => o.Status == "open" && o.Total > 100)
    .OrderByDescending(o => o.Total)
    .Take(20)
    .ToListAsync();

Supported LINQ: Where (==, !=, <, >, <=, >=, &&, ||, !, string.Contains/StartsWith, bool members), OrderBy/ThenBy(Descending), Skip/Take, and .Match(field, text) / .FullText(text). Anything else throws NotSupportedException - drop down to the native ElasticsearchClient.
