    Migration: Indexes defined using client API

    Below there is list of changes to AbstractIndexCreationTask, AbstractMultiMapIndexCreationTask and IndexDefinition.

    Namespace

    Change Raven.Abstractions.Indexing and Raven.Client.Indexes namespaces to Raven.Client.Documents.Indexes.


    AbstractIndexCreationTask and AbstractMultiMapIndexCreationTask

    MaxIndexOutputsPerDocument

    MaxIndexOutputsPerDocument property was removed. A warning is issued instead. Read dedicated about performance hints if you use when fanout indexes

    Sort

    There is no need to explicitly define sorting in definitions of static indexes anymore. RavenDB automatically determines sorting capabilities based on types of indexed values. You can remove Sort method usages from your index classes, such as:

    Sort(x => x.Month, SortOptions.Int);

    Constants.AllFields

    Constants.AllFields constant has been moved to Constants.Documents.Indexing.Fields.AllFields

    FieldIndexing.Analyzed

    FieldIndexing.Analyzed has been renamed to FieldIndexing.Search

    FieldIndexing.NotAnalyzed

    FieldIndexing.NotAnalyzed has been renamed to FieldIndexing.Exact

    IndexDefinition

    Map

    Map property has been removed. Use Maps property instead.

    Field options

    Options as are now defined per field using Fields property.
