strigi-daemon binary package in Ubuntu Xenial arm64

 Strigi is a program for fast indexing and searching your personal data. It can
 gather and index information from files in the filesystem even if they are
 hidden in emails or archives. It comes with a Qt4 GUI, an HTML GUI and a KDE
 GUI.
 .
 Main features:
  * very fast crawling
  * very small memory footprint
  * no hammering of the system
  * clucene backend
  * DBus and socket interfaces are available for communication between daemon
    and search programs
  * simple interface for implementing plugins for extracting information. we'll
    try to reuse the kat plugins, although native plugins will have a large
    speed advantage
  * calculation of sha1 for every file crawled (allows fast finding of
    duplicates)
 .
 This package contains the Strigi daemon
