Comparing Elasticsearch and SharePoint Search On-Premise

Create Powerful, Enterprise-wide Cognitive Search Solutions

We support both Elastic Cloud (Hosted Elasticsearch) and on-premise Elasticsearch.  If you are evaluating enterprise search, you should consider Elasticsearch. Here is a comparison with SharePoint:

Elasticsearch can be a great platform for enterprise search when coupled with BA Insight’s products:

  • 1

    SmartHub –provides a modern, responsive search UI, personalization, and cognitive search capabilities.

  • 2

    Indexing Connectors –Our secure connectors bring content from over 60 enterprise systems into the Elasticsearch index, providing unified views of all knowledge assets.

  • 3

    AutoClassifier – Auto-tagging, metadata generation, and text analytics feed Elasticsearch’s schema, filtering, and faceted navigation, increasing findability.

BA Insight’s products also combine with Elasticsearch and Elastic Cloud to create best-of-breed cognitive search

Benefits of Elasticsearch

  • Sophisticated search capabilities: including real-time indexing, geosearch, pattern search, and search on machine data.
  • High Degree of Control: including direct control of relevance ranking, query processing, and indexing.
  • Open Source: provides assurance of future continuity as well as the ability to change or fix any aspect of the search engine as required.
  • Scale-up: no limits on size of documents or number of items indexed; pay as you grow. If you are hitting the limits of SharePoint search, you can use Elasticsearch to supplement your existing search and present users with a single unified result set through SmartHub .
  • Fast answers: Elasticsearch is noted for quick response times and is notably faster than SharePoint search.
  • Managed Service (with Elastic Cloud): results in lower cost and less work by eliminating the need to deal with servers, software updates, backups, etc.  Elastic Cloud is available on Amazon Web Services and also on the Google Cloud Platform.
