What is ElasticSearch In short, it can be thought of as “search engine software” It provides the realistic potential for you to run your own search engine service (like a Bing or a Google) but with say, private, sensitive, or confidential data/documents that you don’t want on the public web Great extra capability for your company, enterprise, app, startup, client Elasticsearch is an open-source, distributed web application that runs on top of Lucene, and it is written in Java, and it supports REST API Apache Lucene is the best open-source search engine, and probably one of the best search engines available, and holds its own even when compared against the most expensive commercial alternatives Very fast search Accel Frontline Limited.

What makes it unique ? Fast, Incisive Search against Large Volumes of Data On the same hardware, when a relational database query that would take more than 10 seconds using SQL will return results in under 10 milliseconds in case of Elasticsearch. Elasticsearch provides a distributed, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON based document store. Has an real-time analytics engine Kibana and logstash log and event analyzer that compete with very popular tool like Splunk.

Where can we use Elastic ? Enterprise Search Analytics Elastic tool can be used in various Product Search Engine development like: Blog Search Document Search E-commerce product Search People search Site search Elastic as a distributed platform provides two strong tools . Kibana  A tool for Flexible analytics and visualization platform. Logstash An ETL tool to process Any Data, From Any Source www.accelfrontline.com | All Rights Reserved

Elastic in future enterprises Dataset size is always a concern in BigData analysis which often grows exponentially. The real challenge is to figure out a way to store and analyze such a huge amount of data as efficiently as possible and to make that data easily searchable for users, by providing them with advanced queries which usually takes several days to finish. Hence, ElasticSearch, an open-source Java based full text indexing system, can be a robust solution in BigData analysis which allows to query and explore the huge data set in very less time. ElasticSearch can be an ideal solution in BigData analysis, as BigData analysis demands a robust distributed architecture as well. www.accelfrontline.com | All Rights Reserved

Elastic in future enterprises Fuzzy Search This is a semantic approach in ElasticSearch to determine the user's intent, rather than just focusing on keywords (as it’s the approach for most e-commerce shopping carts out of the box). This feature could mean synonyms, spell-correction, field boosting etc. Collectively, these can be thought of as a "Did You Mean?" experience. Speed Most shopping carts utilize relational database out of the box. These are powerful and free, but can be slow, especially if your product catalog is in the tens of thousands. So, ElasticSearch can provide a real boost to the conventional E-commerce Solutions in Next-gen enterprises. Geo-search Features such as store locators, or tagging users in your vicinity are possible with ElasticSearch. Accel Frontline Limited. All Rights Reserved
