Azure Search-Create Index



This is the second post in the series of implementing Azure search. In previous post I described what Azure search is and how can implement it.

As discussed in previous post, implementation of Azure search is four step job.

Let's get started.

Create Index

You can create index from portal as well as code. In this post I will be using the code to create the index and also give the overview to create index from the portal.

Overview from portal

Let's  go ahead and click on Add Index button on overview screen. Here you will see 
  • Name of the Index
  • Fields: You can insert as many fields as you want. You can also select whether it should be searchable, sortable, filterable, etc..

From Code

For this demo I will be using VS 2017
  • Go ahead and create a .NET core MVC product using visual studio.
  • Install Microsoft.Azure.Search nuget package. 
  • From portal 
    • Copy the Name of the Azure Search.
    • Copy the Admin keys from key section.
Now let's write some code
  • Create two variables which will hold the value of azure search name and keys.
  • In Home controller create a private method which will create a search service client.
  • Create a model on which you want search to happen.

You can see in screen shot I have add multiple attribute on each fields which describe what capability I want on those fields for example I want to search, sort on first name and last name. I also added a fields on which I want to add Lucene search and I also specified the analyzer. 
  • Create a method to create a index 

  • Finally, call this method from the About Action. For the simplicity I am calling this method from about method so that when I redirect to the About page index will be created. Let's run the application and navigate to about page. Once About page is loaded we can see in the portal that our index is created. 

This is it we are done with creating an Index. Not let's do step three to import the data for search.

Implement Open API specification in .NET Core Web API using Swagger.

Documentation is always crucial part of development, developers can always check that API is available or not before creating a new one. Swagger is a great framework to use when it comes to API documentation. It's  not only provide the UI but also provide an OpenAPI specification which is used to create client for using the API. Using this specification and Swagger Codegen, you can create client for c#, angular and many more. The purpose of this post is not just to implement swagger but also to describe how you can specify other OpenAPI specification properties like schemes and hosts which is important when you are working with Azure API management. Prerequisites  To follow along you need  Visual studio 2017 Let's Get Started Step 1 : Create a .NET Core API using Visual studio 2017. Step 2 : Remove existing controller and create a new empty controller and name it UserController. Step 3 : Add the following acti

Azure Functions

If you are working on or learning Azure then you must have come across this word called Azure Function. A lot of people are talking about it, so let's understand what it is in very simple language. In this series of posts I am going to explain the following  What is Azure function. Create Azure function from the Azure portal Create Azure functions from Visual studio Trigger and Bindings Create APIs using function with bindings  Publish function on Azure I will also be sharing some use cases so that you can relate where exactly you can use Azure functions. This blog series is not going to be only talking but we will also be doing some hands on. So let's start. What is Azure function? To understand that let's assume, you have a front end application which is developed using some java script framework ex angular, react etc. and you need a functionality to upload a file in blob service and this is it, this is your application (might not be realistic to you bu

Azure Search - Load Data

Image
This is the third post of blog series on Azure search. In previous post I explain how we can Provision Azure service and how we can create Index . In this post I am going to show you how we can load the data in Azure search service. Now you can import the data which is already present in Azure services like SQL, Blob storage etc or you can import data from other service using code. If  you use existing service, it is going to be a pull operation where indexer will crawl over your data and create indexes. Here I will be explaining how we can push the data to Azure search using .NET SDK. Before jumping on code, let's take a moment and understand what are actions. Actions are nothing but the operations performed on data on the service, these operation can be Upload : Will upload a new record in index. Delete : Will delete an existing record. Merge : Will merge the records with the existing one. Merge Or Upload : Merge if exist otherwise upload the document. Now
