Full-text Search in Intermediate Data Storage of FCART

The speed of full-text search directly affects the process of text analysis. Search engine creates a text index, which is used for fast full-text search. Solr and ElasticSearch are two popular search engines. A text analysis system requires fast implementing searching and indexing at the same time. This paper describes preprocessing workflow of the analysis system called Formal Concept Analysis Research Toolbox (FCART) and experiment of searching and indexing social networking service data at the same time. Results of the experiment show which search engine is better as the core of FCART search subsystem.
