xapers is:

Xapers is a personal document indexing system, geared towards academic journal articles. Think of it as your own personal document search engine, or a local cache of online libraries. It provides fast search of document text and bibliographic data and simple document and bibtex retrieval.

Document files (in PDF format) and source identifiers (e.g. DOI) are parsed and indexed into a Xapian search engine. Document text is extracted from the PDF and fully indexed. Bibliographic information downloaded from online libraries is indexed as prefixed search terms. Existing bibtex databases can be easily imported as well, including import of pdf files specified in Jabref/Mendeley format. Documents can be arbitrarily tagged. Original document files are easily retrievable from a simple curses search UI. The command line interface allows for exporting bibtex from arbitrary searches, allowing seemless integration into LaTeX work flows.
