  • 'google-like' search engine for files on my NAS
    If so, then https://solr.apache.org/ can be a solution, though there's a bit of setup involved. Oh yea, you get to write your own "search interface" too which would end up calling solr's api to find stuff. Source: over 3 years ago
  • Search engine.
    Developers will use their SQL database when searching for specific things like client names, product names, or address search. Now when you want to level up from there and search all tables you better off using a separated server with a specific program like https://solr.apache.org/. Source: almost 4 years ago

  • Remarkable update 2.14
    Finally if you really want a full fledged solution the most popular are good old Sphinx http://sphinxsearch.com or Apache Solr https://solr.apache.org but as these take a bit of time to setup I'd make sure that's truly needed.

  • Owl3D - Create 3D photo and video with 1 click on Oculus Quest
    As a fellow developer, I would have to recommend all of the above. However in terms of priorities, I'd suggest using a standard tag system first and then branching into text search which is a bit more complicated. If you've never made a search function before or simply never made one for a large scale media app, I'd recommend checking out Solr. Source: over 4 years ago
  • Need CLI tool that can handle large txt files and another tool that can conduct a lightning fast search of disk files.
    For fast searching, it usually requires indexing the files in question. There are a number of text-file indexing solutions, many of which use xapian, sphinx, or lucene/solr under the hood. Based on conditions (watching files/directories, cron jobs, new-mail triggers, etc), they'll add/remove files to the index, and you can then use a corresponding command to compose queries across that data. If it's indexed, it... Source: over 4 years ago

  • Probing Text Data Using PostgreSQL Full-Text Search

  • A Handbook to Implement Fuzzy Search in PostgreSQL
    PostgreSQL has a lot of advanced extensions and indexes to speed up the same. But one should keep in mind that these have their own limitations in terms of speed and might not work with languages other than English/multi-byte encoding, such as UTF-8. However, these fill the critical gap where the functionalities mentioned are necessary, but we cannot go for a full-fledged search solution such as Solr/Elastic Search. - Source: dev.to / almost 5 years ago
  • Advice needed on best way to develop a website that displays lots of data as different subpages.
    The bigger problem is the search capability. If you had a typical dynamic website with a database and some backend (be it PHP or any other language) you might get away by implementing the search capability through various SQL queries. However that often doesn't scale well and is complex. Personally I would recommend to just immediately use something like Apache Solr. Source: about 5 years ago

Summary of the public mentions of Apache Solr

Apache Solr continues to maintain a strong presence in the realm of open-source enterprise search solutions. As a robust search platform entrenched in the Apache Lucene project, Solr is recognized for its scalability and adaptability to high-volume traffic environments. It is often lauded for its near real-time indexing capabilities, ensuring the delivery of fresh and relevant search results, which is a crucial factor for many enterprises looking to maintain updated content accessibility.

A critical advantage of Solr is its extensibility through a plugin architecture, allowing organizations to tailor the search engine to specific requirements. This flexibility appeals particularly to businesses with unique needs that are not met by out-of-the-box solutions. The platform supports various file formats, including JSON, XML, CSV, and binary data, facilitating diverse indexing and querying processes through HTTP protocols.

Comparative analyses among its peersโ€”particularly ElasticSearch, a close competitorโ€”highlight Solr's strengths and limitations. While described as slightly slower than ElasticSearch, Solr is touted for handling static data effectively. The Solr system relies on global caching mechanisms, which introduce latency when data changes require cache refreshes. This contrasts with ElasticSearch's segment-based approach, offering more fluid updates and potentially swifter responses.

Despite these aspects, Solr is favorably reviewed as a self-hosted alternative to other managed services. Its open-source nature makes it an attractive choice for organizations that prefer to maintain control over their search infrastructure. In discussions comparing it to Algorithms like Algolia, Solr holds its ground with a balance of comprehensive features and cost efficiency as an open-source tool. Its customization capability extends beyond standard functionalities, allowing users to implement sophisticated search solutions tailored to specific business contexts.

Solr's application potential spans various use cases, from processing extensive text-based documents and handling diverse data types to supporting advanced data searches in complex environments. Many professionals highlight Solr's proficiency in managing large-scale search projects, operating efficiently with datasets extending into the billions of entries.

In conclusion, public opinion generally favors Apache Solr for its reliability, extensive customization options, and suitability for large-scale, robust search implementations. While it presents a learning curve and setup challengeโ€”factors that might discourage less experienced usersโ€”its comprehensive feature set remains attractive to enterprises seeking a scalable and customizable search platform. As the industry continues to evolve, Solr stands as a steadfast choice for businesses keen on building sophisticated search capabilities internally.
