Nepoogle

WARNING!!! Nepoogle needs at least KDE 4.10.1 and Nepomuk2 python bindings to work. This bindings are available here: http://quickgit.kde.org/?p=scratch%2Fsedwards%2Fpykde4nepomuk2.git

Nepoogle is a search utility for Nepomuk inspired in Google's search syntax. It has it's own SPARQL query builder engine to obtain more powerful queries but supports Nepomuk's query parser, like KRunner or Dolphin, too.

An install and uninstall scripts are available to install all required files.

Functionalities:
-NEW: Parentheses supported in queries.
-NEW: basic edition capabilities.
-Logical operators "and", "or" and several comparison operators supported.
-Many shortcuts and commands, read help for full list and description.
-Multiple links and operations available.
-Drag&drop support.
-Resource viewer with navigation system, image support and multimedia player (video player seems to work only with GStreamer Phonon Backend with video support).
-A cache system with manual refresh using F5 key.
-Three different query engines, two internal and Nepomuk::Query::QueryParser().
-Supports Nepomuk TVNamer, http://kde-apps.org/content/show.php/Nepomuk+TVNamer?content=148910.
-Full support to UTF-8.

Known bugs that can not be fixed:
-Volume is reset to max volume on track change: this is a bug in QtWebKit, current javascript code it's working in Chrome and Firefox. Any help to find a workaround would be appreciated.
-Some mp3 files sounds awful: this is a bug in GStreamer.

Search tips:
-Ask specific questions and if you get no results then try more general questions:
"e" -- you will get a lot of results and a slow query
actor:e -- more optimized version if you are looking for an actor

-If you know exactly the word you are looking for "+" will improve performance and the results you obtained but search is then case sensitive:
performer:+"Fleetwood Mac" -- query works
performer:+"fleetwood mac" -- query fails
performer:"fleetwood mac" -- query works but is more slow

-Regular expressions are your friends:
^word -- string begins with "word"
word$ -- string ends with "word"
^this.*word$ -- string begins with "this" and ends with "word"

-Use quotation marks if you need to search for special characters or spaces:
"Singin' in the Rain" -- because character "'" and spaces
"^file:///storage/movies" -- because character ":"
"f(x)" -- because parenthesis
"Peter Gabriel" -- without quotation marks nepoogle will search for "Peter and Gabriel"

-Use parentheses to build powerful queries:
movies: and (actor:gosling or actor:stone) and (releasedate:2011 or releasedate:2013)

-With e0 prefix Nepomuk::Query::QueryParser() engine is used rather than internal engine:
"e0 movies" -- display same results than KRunner or Dolphin.

Future development:
-External configuration file.
-Remote queries.
