About:
Pazpar2 is a metasearching middleware webservice that provides a unified API for searching across multiple heterogeneous databases and information sources. It normalizes search results and presents them through a simple XML interface, enabling the creation of powerful search portals without managing complex backend connections.
Key Features:
  • Metasearch aggregation from multiple sources
  • Result normalization and de-duplication
  • Simple XML-based web service interface
  • Support for Z39.50 and SRU protocols
  • Relevance ranking and faceted results
Use Cases:
  • Building unified search portals for libraries and institutions
  • Aggregating results from multiple database subscriptions
  • Creating custom metasearch applications
Alternatives:
  • Solr – Full-text search platform requiring data indexing, while Pazpar2 provides real-time metasearch without data duplication
  • Elasticsearch – Distributed search engine focused on indexing, versus Pazpar2's live query federation approach
