Best Full-Text Search Engines to Maximize Search Experience for Your Users in 2021

Most applications and websites that operate vast and ever-increasing volumes of data cannot serve their customers well without implementing modern full-text search engines. Compared to traditional relational databases, full-text search engines allow for a much more relevant search and can quickly process larger quantities of structured, semi-structured, or unstructured texts using specific words or word combinations.

Today, there is no shortage of capable full-text search engine solutions in the market. Some of them are proprietary technologies, while others are open-source products. This post explains the full-text search concept and reviews the five best publicly available and proprietary solutions. Read on to find the one that meets your business needs in full.

What Is Full-Text Search?

Full-text search is a method of searching a single text or a collection of texts stored on a computer or in a full-text database. When processing an advanced linguistic text query, the search engine examines and analyzes all the words in every applicable document, seeking to match the criteria provided by the user.

As static sites become more of a trend and replace dynamic database-driven online resources, full-text search systems are turning into a much-needed, customizable tool for performing complex search operations.

The Benefits of Using a Full-Text Search Engine

The reasons for implementing a full-text search system are many and varied. Here are just a few advantages users can derive from such solutions:

  • High query-processing/result-retrieving speed. The use of full-text search ensures a high speed of processing the user’s text query and obtaining accurate results for a vast number of documents across an extensive text database.
  • Great accuracy and precision. Thanks to their highly sensitive recommendation algorithms and advanced relevancy ranking for organizing results, full-text search solutions provide a more accurate, personalized search experience for the user.  
  • Room for customization. The search logic and criteria of such solutions are flexible and can easily be configured to match the user’s more specific needs. The best solutions provide extensive support for keyword search, Google-style syntax search, Boolean operator search, etc.
  • Support of static websites. Employing a full-text search solution ensures an improved experience for the user of static websites where the lack of dynamic features can make searching for a piece of content difficult, lengthy, and rather sloppy.
  • Support of mobile applications. Modern mobile apps require quick and sophisticated search capabilities. Full-text search products implemented in mobile applications will allow to quickly and efficiently index and search all the documents, providing the user with accurate and relevant results.

Full-text search is not always the best possible technology for a website or app to rely on, and in some situations, a relational database with its excellent storing and structured data-manipulating capabilities will offer more measurable and successful results.
