Solr

Things to do with Solr

"Major features include full-text search, hit highlighting, faceted search, real-time indexing, dynamic clustering, database integration, NoSQL features and rich document handling." - Apache

Solr's index is called an "inverted index" because it inverts a page-centric data structure (page->words) to a keyword-centric data structure (word->pages). Solr stores this index in a directory called index in the data directory. See Basic Solr Concepts for a comprehensive definition and context.

In Solr, a Document is the unit of search and index. But in simple terms "In database terminology, a Document corresponds to a table row, and a Field corresponds to a table column."

Fields, filters, tokenizers
