Queries

Feature

Create a query to filter or to use in filter query

How to

1. Use some feature that allow use SearchQuery<> (i.e. Filter or FacetQuery)

2. Configure query

    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
         // cat:"some category"
        .Filter(q => q.Categories, query => query.EqualsTo("some category"))
        .Execute();

1. Optionally use a chain of methods

    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
         // cat:"some category" OR features:("feature1" OR "feature2")
        .Filter(q => q.Categories, query => query
            .EqualsTo("some category")
            .Or(nested => nested
                .Field(f => f.Features)
                .Any("feature1", "feature2")))
        .Execute();

Simple cases

Use case	How to	Query generated
Query to find all informed values (conditional AND)	query.Field(f => f.Categories).All("category1", "category2")	cat:("category1" AND "category2")
Query to find some of informed values (conditional OR)	query.Field(f => f.Categories).Any("category1", "category2")	cat:("category1" OR "category2")
Query to find something starts with informed value	query.Field(f => f.Categories).StartsWith("c")	cat:"c*"
Query to find exact informed value	query.Field(f => f.Categories).EqualsTo("category1")	cat:"category1"
Query to find negate informed value	query.Field(f => f.Categories).NotEqualsTo("category1")	NOT(cat:"category1")
Query to find someting in informed range	query.Field(f => f.Price).InRange(1, 10)	price:[1 TO 10]
Query to find someting greater than informed value	query.Field(f => f.Price).GreaterThan(1)	price:[1 TO *]
Query to find someting less than informed value	query.Field(f => f.Price).LessThan(1)	price:[* TO 10]

Complex queries

Use case	How to	Query generated
Query expression isolating in a group	query.Group(price=> price.Filed(f => f.Price).InRange(1, 10).Or(popularity => popularity.Field(f => f.Popularity).GreaterThan(5)))	(price:[1 TO 10] OR popularity:[5 TO *])
