Search, filter, and browse any set of documents. LookingGlass includes full text search, category filters, and date queries all through a nice search interface with an Elasticsearch backend. LookingGlass also supports customizable themes and flexible document view pages for browsing and embedding a variety of document types. LookingGlass requires DocManager so that it can interact with Elasticsearch. LookingGlass can be used in combination with Harvester for crawling, parsing, and loading documents and automatically turning them into a searchable archive. However, it also works well as a standalone archiving tool.
