DSL

Example:

[SetUp]
public void setup() {
    Solr.Connection = new SolrConnection("http://localhost:8983/solr");
}

[Test]
public void QueryById() {    
    ISolrQueryResults<TestDocument> r = Solr.Query<TestDocument>().By("id").Is("123456").Run();
}

[Test]
public void QueryByRange() {
    ISolrQueryResults<TestDocument> r = Solr.Query<TestDocument>().By("id").Between(123).And(456).OrderBy("id", Order.ASC).Run();
}

[Test]
public void DeleteByQuery() {
    Solr.Delete.ByQuery<TestDocument>("id:123456");
}

Run() is the explicit kicker method. There are some more examples in the tests.

There's also a query-building fluent interface, some examples:

Query.Simple("name:solr"); // name:solr
Query.Field("name").Is("solr"); // name:solr
Query.Field("price").From(10).To(20); // price:[10 TO 20]
Query.Field("price").In(10, 20, 30); // price:10 OR price:20 OR price:30
Query.Field("name").HasAnyValue(); // name:[* TO *]

These can be used anywhere where a ISolrQuery is accepted, i.e.:

ISolrOperations<Product> solr = ...
solr.Query(Query.Field("name").HasAnyValue());

They can also be mixed with boolean operators:

ISolrOperations<Product> solr = ...
solr.Query(Query.Field("name").HasAnyValue() && Query.Field("price").Is(0));
