The way input text is broken into tokens heavily influences how people will then be able to search for that text.įor instance, sentences beginnings and endings can be identified to provide for more accurate phraseĪnd proximity searches (though sentence identification is not provided by Lucene.NET). Of breaking input text into small indexing elements – tokens. Plain text passed to Lucene.NET for indexing goes through a process generally called tokenization. Lucene.NET does not care about the Parsing of these and other document formats, and it is the responsibility of theĪpplication using Lucene.NET to use an appropriate Parser to convert the original format into plain text before passing that plain text to Lucene.NET. ParsingĪpplications that build their search capabilities upon Lucene.NET may support documents in various formats – HTML, XML, PDF, Word – just to name a few. Lucene.NET, an indexing and search library, accepts only plain text input.

It supports AIX, HP-UX, Linux, Solaris, Windows, z/OS.API and code to convert text into indexable/searchable tokens. It accepts all operating systems having JVM. It is considered better than Elasticsearch in terms of ranking.
It is considered less than IBM DB2 in terms of ranking. It has ADO.NET, JDBC, ODBC, Xquery, JSON style queries. It is implemented in C and C++ languages. It has ES-Hadoop connector type map reduce. It has concept of transactions satisfying ACID properties. Primary database model is document store and RDF store in IBM DB2. The primary database model is a search engine.

It has a commercial license and has high scalability.ĭifference between Elasticsearch and IBM DB2 :Įlasticsearch is a search and analytics engine based on Apache Lucene. It is extremely reliable and is supported by Linux, Unix and Windows operating systems. It has efficient backup facilities and is considered very secure. It works on the principle of ACID and has high flexibility and performance.
It has enhanced capabilities for performing transactions. It is considered as a family of database management products which are build for AI. It is a relational database which was developed by IBM in 1983. It has high scalability and the speed of performing a action is also high which makes it a easy and fast tool for data analysis, processing and visualization. It is a distributed search and analytics engine.It is open source and can be used for all types of data.It is implemented in Java programming language and supports all operating systems having java virtual machines (J.V.M).It is the main component of Elastic Stack, which is a open source application for data analysis and visualization.
