What is a query in ElasticSearch?

A query in ElasticSearch is a request made to the ElasticSearch system for extracting specific information or data from the indexed documents. It is a set of parameters and conditions that help to filter and search for relevant documents based on specific criteria. ElasticSearch queries can be highly flexible and allow for simple searches as well as complex queries involving multiple conditions, aggregations, and sorting. The queries can be executed using the RESTful API provided by ElasticSearch or using query DSL (Domain Specific Language) for more advanced querying.

How to define mappings in ElasticSearch on Hostinger?

To define mappings in ElasticSearch on Hostinger, you can follow these steps:

1. Log in to your Hostinger account and navigate to the ElasticSearch section.
2. Create an ElasticSearch index where you want to define mappings if you haven't already done so.
3. Once you have created the index, click on the "Manage" button next to it to access the index management page.
4. On the index management page, you will see the "Mappings" tab. Click on it to define the mappings for your index.
5. In the mappings tab, you will find a text editor where you can define the mappings in JSON format.
6. Start by defining the properties of your index. Each property represents a field in your index. For example, if you have a field named "title" of type "text", you would define it as follows:

1
2
3
4
5
6
7

{
  "properties": {
    "title": {
      "type": "text"
    }
  }
}

1. You can also define additional properties such as the analyzer, index options, and more, depending on your requirements. Refer to the ElasticSearch documentation for more details on available options.
2. Once you have defined your mappings, click on the "Save Changes" button to apply them to your index.
3. ElasticSearch will then validate your mappings and apply them to the index. You can check the status of the mapping application in the "Indexing Status" tab.

That's it! Your mappings are now defined in ElasticSearch on Hostinger.

What is a sorting operation in ElasticSearch?

In ElasticSearch, a sorting operation is a process of arranging search results in a specific order based on one or more fields. It allows you to specify a field or multiple fields to sort by, as well as the sorting order (ascending or descending). ElasticSearch uses algorithms to efficiently sort and retrieve documents based on the specified sorting criteria, which can greatly enhance the search experience and relevance of results. Sorting can be performed on numeric, text, date, and other data types present in the indexed documents.

How to enable caching in ElasticSearch on Hostinger?

To enable caching in Elasticsearch on Hostinger, you can follow these steps:

1. Log in to your Hostinger control panel and navigate to the Elasticsearch section.
2. Click on the "Manage" button next to your Elasticsearch instance.
3. In the left sidebar, click on the "Indices" tab.
4. Choose the index that you want to enable caching for and click on the "Actions" button next to it.
5. From the drop-down menu, select "Edit settings." This will open the index settings editor.
6. In the "Index settings" section, add the following lines to enable caching:

1
2
3

"index.cache.query.enable" : true,
"index.cache.query.max_size" : "1000",
"index.cache.query.ttl" : "10m"

The first line enables caching for queries, the second line sets the maximum cache size to 1000. The third line specifies the time to live for the cache entries, which is set to 10 minutes in this example. You can adjust these values based on your needs.

1. Click on the "Save" button to apply the changes.

Once caching is enabled, Elasticsearch will start caching query results, which can improve search performance for repeated queries on the same index.

Note: Enabling caching in Elasticsearch may consume more memory, so make sure you have enough resources available on your Hostinger hosting plan.

5. Choose the Elasticsearch version you want to use and click on the "Save" button.
6. After saving the settings, you will see the Elasticsearch details on the same page, including the Elasticsearch host, port, and index name.
7. Make note of these details as you will need them to connect to Elasticsearch.
8. To use Elasticsearch in your application, you need to configure it accordingly. This might involve updating the configuration files or using Elasticsearch clients/libraries specific to your programming language.

Note: The availability of Elasticsearch on Hostinger depends on your hosting plan. It may not be supported in some plans.

What is aggregation in ElasticSearch?

Aggregation in ElasticSearch is a functionality that allows you to summarize or group data in a search query. It enables you to perform calculations, statistics, and analytics on your data to get valuable insights. Aggregations can be used to obtain counts, average values, maximum or minimum values, statistical distributions, and more. They can also be combined with queries to filter and narrow down the data before performing the aggregation. Aggregations are an integral part of data exploration and visualization in ElasticSearch.
