Elastic Search

DevArchitecture comes with ElasticSearch support. It uses Nest library for ElasticSearch support. You can use https://github.com/elastic/elasticsearch-net for Nest library.

Classes related to ElasticSearch are located in the ElasticSearch folder under Utilities in the Core layer.

To connect to the ElasticSearch server, the fields in the ElasticSearchConfig module in the appsettings.json file must be filled.

ElasticSearch operation operations are defined in the IElasticSearch interface. ElasticSearchManager class is used as base. DevArchitecture supports the operations of indexing, adding data, adding multiple data, updating data, deleting data, listing data, listing data by field name and listing data by query on ElasticSearch.

DevArchitecture ElasticSearch operations

Not: ElasticSearch' de Insert işleminde ilgili index'in oluşturulup oluşturulmadığı kontrol edilmelidir. GetIndexList() metodu ile mevcut Indexlerin listesine erişilir. Eğer index yok ise CreateNewIndexAsync() metodu kullanılarak index oluşturulabilinir.

Note: In ElasticSearch, it should be checked whether the relevant index is created in the Insert operation. With the GetIndexList() method, the list of available Indexes is accessed. If there is no index, the index can be created using the CreateNewIndexAsync() method.

Note: Index names must be lowercase

ElasticSearch operations use their own ("/_id") field for ElasticSearch operations. This field is the Nest.Id field in the Nest library. This field is defined in DevArchitecture in the ElasticSearchModel class. ElasticSearchInsertManyModel, ElasticSearchInsertUpdateModel, which are used for other CRUD operations, use ElasticSearchModel class as base class. In addition, the IndexName field used in each CRUD operation is also defined in this base class.

ElasticSearchGetModel class is used as a response model in Get operations made over ElasticSearch. This model has the generic type property. By default, it returns the value of ElasticSearch ("/_id") and the object of the class type defined in the generic type.
