Key Features
- Lucene and Solr core: Uses Apache Lucene and Solr for indexing and querying
- enabling scalable full text search across large collections you host yourself
- Multi format indexing: Designed for heterogeneous sources and file formats so teams can search PDFs and documents in one interface
- Integrated research tools: Adds discovery monitoring and analytics concepts to support exploration beyond simple keyword lookup
- Faceted navigation: Use metadata and filters to narrow results and explore subsets efficiently within large mixed corpora
- Extensible modules: Ecosystem includes optional components like graph exploration for relationships discovered in extracted entities
- Citation maps: Visualize connections between papers so you can see clusters and influential work rather than reading in isolation
- Collections and projects: Save papers into collections and organize them as projects to keep a literature review structured
- Author exploration: Follow authors related to your collection to discover their other papers and see how networks evolve
- Research alerts: Get alerts tied to your collections so new relevant papers are suggested without repeating manual searches
- Seed based discovery: Start from up to 50 input papers in the free plan and expand outward using related work suggestions
- Large coverage claim: The pricing page states searches span 280 plus million articles which helps broad discovery across fields
Use Cases
- Internal knowledge search: Index policies manuals and procedures so staff can retrieve answers quickly using full text and metadata filters
- Research corpus exploration: Build a searchable archive of papers reports and PDFs for discovery workflows and literature review tasks
- News monitoring: Index news and track topics over time to support monitoring and investigation with a searchable history
- Case file investigation: Search across heterogeneous case materials and attachments to locate evidence and related entities faster
- Archive digitization search: Make older document archives searchable by indexing extracted text and metadata from stored files
- Compliance discovery: Search contracts and policies across repositories to find clauses and obligations during audits and reviews
- Literature review start: Add a few seed papers then use citation maps to find foundational work and recent branches quickly
- Thesis topic discovery: Explore clusters around an idea and identify gaps where fewer papers connect or methods are missing
- Author tracking: Follow key authors from your collection to discover their latest publications and related collaborators
- Staying current: Use collection alerts to surface new relevant papers so you keep up with fast moving fields efficiently
- Cross discipline scan: Start with one paper then expand to adjacent domains to find methods you can transfer to your project
- Reading list curation: Build a structured reading list inside a project so you can prioritize what to read and why it matters
Perfect For
researchers, librarians, knowledge management leads, compliance analysts, investigative teams, IT administrators, data engineers maintaining Solr, organizations needing on premises search
researchers, graduate students, librarians, lab managers, systematic review teams, R and D analysts, academics who need citation maps alerts and structured collections
