What We Do

Indexing Development

Make application stable with increased speed of indexing and removing latency of bringing data into elastic search. Create domain & problem specific optimized index creation.

Relevancy Tuning

Relevancy Tuning will help your users in getting desired results as fast as possible with fewer clicks or words. This will enable you in evaluating how good the current search is.

API Development

Provide fast, scalable, robust API endpoints, which connect UI to Elastic search queries. Close development of API endpoints and queries will help in avoid many integration bugs.

Performance Tuning

Performance Tuning will help in understanding the health of the machines, health of the cluster. Improving those will improve the overall experience of end users.

Solutions

Indexing Icon

Indexing

  • Data stored in Lucene Inverted Index format
  • Easy to replicate the index from one node to another
  • Advance concepts like Field cache helps in making the aggregation and sorting faster
  • More flexibility in terms of managing the indices like creating indices based on dates, categories etc.

Schema & Mapping

  • Elasticsearch is “schema-less” by nature - “Configure only when you really need to”
  • Dynamic Mapping- Automatically apply generic mapping definitions to types which do not have mappings predefined.
  • While indexing any “unseen” document, a mapping is dynamically created for it
  • Dynamically elastic stores both versions of data

Relevancy

  • Boosting the rank of document from query side as well as during indexing time
  • Proximity for relevance-we can get the results by setting the proximity in our query (For ex: minimum_should_match = 30%).
  • While indexing any “unseen” document, a mapping is dynamically created for it
  • N-Gram Partial Matching functionality for getting the relevant results by providing the length

Percolator

  • Used for alerting , monitoring and document filtering based on the queries
  • The percolator and most of its features work in real-time, so once a percolate query is indexed it can immediately be used in the percolate API.
  • Percolator can also help in auto tagging documents as they are getting indexed which might help in creating better navigation and user experience.

Sizing and Performance

  • OOTB clustering is simple, two instances with same cluster name and in the same network will automatically connect.
  • Support for AWS discovery if on AWS system.
  • Can be configured to perform Unicast and multicast discovery.

Snapshot and Restore

  • ES provides different ways to get backup of indices as FS, AWS, HDFS.
  • The snapshot process is get executed without blocking index.
  • The snapshot process is incremental.
