por Search engines or servers They are widely used in the world of big data., thanks to facilitation systems to carry out a consultation. They have a great capacity to manage information and improve their interaction with the user. The queries of ElasticSearch are a fundamental factor for the use of this Big Data search server.
Now, if you are here it is because you have doubts about what the queries in ElasticSearch, so this post is ideal for you! Since in the development of this, We will explain to you what the queries in ElasticSearch and how they are implemented within the Big Data world.
What are ElasticSearch queries?
A query or search (in Spanish) refers to a information query request that is developed in this type of search servers such as ElasticSearch. The collection of documents related to the concern presented and the results that the platform returns are also part of that search.
Besides, the queries from ElasticSearch have a series of various dynamics and strategies to achieve its main objective of providing the information needed from the database. In this way, the query and its results are optimally enhanced and processed.
On the other hand, to make a query It is necessary to carry out the following steps:
Make a setup of the documents to be indexed. From there, you must use the API (Search API) to perform the search. Now, you can add (Aggregation) your stored datawhich will convert your information into metric, statistical or analytical values that will make it easier to understand the query and its results. Once you have done this, you must set the type in the console query what you need for your information query. Now, within the types of queries from ElasticSearch you will find: field _allby fields, by bootswith fuzziness or with wildcards.In real time, ElasticSearch from its API It will give you the ten documents that match your search.
Types of ElasticSearch queries
As we have already mentioned, searching for data in ElasticSearch has multiple query strategies or dynamicssince in this way the effectiveness of the results returned by this server is enhanced.
For this reason, below we share What are the main types of queries of ElasticSearch and, briefly, what they consist of:
query in the countryside _all: This type of query is the most used, since It has all the information of all the fields.query by fields: is the second type of query most used and consists of select certain fields once the consultation is going to be carried out.query with boosts: it’s based on enhance certain fields to make the search faster and more agile.query with fuzziness: This is carried out when the user does not know the phrase or the complete text to be consulted and the search server chooses to yield results that are closest to what was stated.query with wildcards or wildcards: This type of search consists of generate wildcards within fields to facilitate the results of the query.
Keep learning about Big Data
Through this post, you have been able identify what are queries of ElasticSearch and how they work to carry out the classification and search of information. However, this process is part of a wide variety of strategies for managing Big Data.
