Apache Solr vs Manticore Search

Apache Solr is a free, open-source, self-hosted search platform built on Apache Lucene. It provides full-text, vector, geospatial, and hybrid search through a REST query interface. Documents can be sent over HTTP as JSON, XML, CSV, or binary, with results returned in those formats. Matching supports phrases, wildcards, joins, and grouping; discovery tools include faceting, autocomplete, spelling suggestions, hit highlighting, and result clustering. Solr distributes indexing, replicates data, balances queries, and supports automated failover and recovery. Apache Tika integration extracts rich content such as PDF and Microsoft Word files. Its administrative interface controls instances and exposes cluster state, logs, threads, and metrics. Listed security capabilities include SSL, authentication, and role-based authorization. Solr runs on Linux, macOS, and Windows, with API access, and is licensed under Apache License, Version 2.0. The project describes use from weekend projects to global enterprises. Releases are not scheduled in advance, and versions below 9.10 are end of life without further updates. The Apache Solr plan is free.

Manticore Search is an open-source database for full-text, vector, hybrid, real-time indexing, and analytical queries. Applications can use SQL, the MySQL protocol, or JSON APIs. Full-text tools include fuzzy matching, query suggestions, filtering, faceting, stemming, lemmatization, synonyms, and highlighting. Vector search uses KNN with HNSW and supports cosine similarity, inner product, and squared L2 distance. Manticore can read from MySQL, Postgres, MSSQL, ODBC, XML, CSV, and TSV, and lists integrations such as Logstash, Apache Superset, Grafana, Fluentbit, Kibana, Vector.dev, and Elasticsearch dump. Installation options cover Linux, macOS, Windows, and Docker. The site recommends WSL2 for compatibility; native Windows binaries require Docker for Manticore Buddy and do not support replication. Authentication and authorization are opt-in. Binary API connections are not secured by SSL, and the manual advises keeping API-capable listeners off the public Internet. The free Community plan includes public support channels and a configuration review. Standard and Enterprise support plans have prices available by inquiry.
