Description:
 Strigi Desktop Search

Here are the main features of Strigi:
very fast crawling
very small memory footprint
no hammering of the system
pluggable backend, currently clucene and
hyperestraier, sqlite3 and xapian are in the works
communication between daemon and search program
over an abstract interface with two
implementations: DBus and a simple unix socket.
Especially the DBus interface makes it very easy
to write client applications. There are a few
sample scripts in the code using Perl, Python, GTK
and Qt. Writing clients is so easy that any Gnome
or KDE app could implement this.
Aditionally, there is a 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.
Strigi also has calculation of sha1 for every file
crawled which allows for fast finding of duplicate
files.

Changelog:
 0.5.8
 - Improve quiting latency of the most important
analyzers. Now Strigi reacts more quickly when you
tell it to stop indexing.
 - Add a tool to analyze the analyzer latency
profile and find analyzers that have a high
latency.
 - Bring field names in line with the Xesam
ontology.
 - New analyzers for avi, wav, dds, rgb, sid and
ico file types.
 - Fix deepgrep (finally working again since
0.5.2) and extend the number of fields deepgrep
searches in. Now it also searches in fields that
are passed as "unsigned char*" to the IndexWriter,
but only if they are not registered as being
binary fields.
 - Install two headers that provide metadata
information about field types. Basically, these
classes publish the ontology that strigi uses.
 - Fix a problem with CLucene throwing
CLuceneError. Because of -fvisibility=hidden, the
code did not recognize CLuceneError and caused it
to fall through, thus crashing programs using
libstreamanalyzer. A unit test to avoid the
problem from reappearing has been added.
 - Fix for system where setenv() is not available
(for instance windows). Hopefully those systems
have putenv() :)
 - Remove support for starting strigidaemon with
an arbiratry index type and index dir, but add an
option to use a different configuration file. This
effectively gives the use the same possiblities.
 - Fixes to the build system that allow strigi to
be built and tested as part of a larger project
(e.g. kdesupport).
 - 'strigicmd listFiles' now can be used to
retrieve all files/dir indexed under a certain
path
 - Added for support for Gentoo-way compilation
flags. Implemented more consistent and pretty
optional dependency handling.
0.5.7 
 - use plugins instead of shared libraries for the
indexer backends
 - lots of bugfixes and cleanups
 - allow backends to be used in RAM by using
':memory:' as the index name
0.5.6
 - Added Xesam User Language parser. Now it will
be possible to handle Xesam UserLanguage queries
(http://wiki.freedesktop.org/wiki/XesamUserSearchLanguage).
 - Replaced .ini-based ontology parser with
RDF/XML one.
 - Updated strigicmd: now it's possible to perform
searches formulated
 following xesam userlanguage specifications.
 - Improved ontology introspection API: properties
and classes now have child lists and applicable
classes/properties lists.
 - change IndexReader::getFiles to
IndexReader::getChildren.
 - removed IndexReader::documentId and
IndexReader::mTime.
 - loads of build issues fixed
 - added a script that helps you to find the patch
that broke a unit test
 - add fieldname for document content per the
Xesam standard.
 - lots more
0.5.5
 - GUI now uses a .ui file making future
improvements much easier
 - install detection script for ease of use in
other cmake projects
 - modifying the signature of endAnalysis to
endAnalysis(bool complete) 
   for StreamLineAnalyzer, StreamEventAnalyzer,
and StreamSaxAnalyzer
 - add a function to AnalyzerConfiguration that
tell how many bytes can 
   be read at most from a stream
 - add an SAX analyzer plugin that extracts the
namespaces used in XML
   documents. With this it possible to get all XML
documents that contain e.g.
   Chemical Markup Language or Dublin Core.
 - add a stream for changing the encoding of an
incoming stream on the fly
 - use the new encoding stream to do better email
parsing
 - add m3u stream analyzer.
 - add simple test program for strigi xesam query
builder. It loads a file
   containing the xesam query. It converts the
xesam query into a Strigi::Query
   object. It serializes the Strigi::Query object
to xml for e.g. quality
   control.
 - add xesamquery option to strigicmd: now it's
possibile to make queries
   using Xesam language.
 - add XesamQueryLanguage queries support. Now is
possibile to translate
   xesam queries formulated using
XesamQueryLanguage into Strigi::Query objects.
 - add a cgi executable that takes
multipart/form-data and outputs an analysis
   of the data as xml
 - give xmlindexer the ability to read from stdin
 - big improvement in parsing ms word files
 - better input sanity checking. thanks to zzuf
for reporting the errors
 - cleanup of private variables in classes by
introducing a d-pointer

0.5.4
 - simplify PollingListener by letting it reuse
code from DirAnalyzer
 - improve parsing speed by reading incrementally
large blocks and only if no throughanalyzer is
ready yet
 - extract more data from ogg and ID3 files
 - new registerField(fieldname) function that gets
additional data from the
   ontology
 - support of indexwriter calls: addValue(index,
field, data, size),
   addValue(index, field, double_value) to CLucene
backend.
 - enable passing of "Tokenized" flag parameter to
CLucene backend
 - support for the Keyword Terms which are not
tokenized during queries
 - handling of optional indexing flags, which are
loaded from the ontology
 - handling of cardinality constraint when
indexing
 - add keyword query type which allows for using
keywords that are not split
   up. e.g. chemistry.molecular_formula#"C 4 H
10". basically "#" sign tells --    do not
tokenize
 - parse the userlanguage wrapped in xesam query
language xml
 - add searialization to xml for Strigi::Query and
Strigi::Term, useful for
   debugging purposes
 - add types from the xesam dbus interface to
strigitypes.h
 - add support for gif files
 - add support for analyzing jpeg files.
 - add prioritized, multithreaded queue for
incoming requests
 - add option --lastfiletoskip to diranalyzer and
xmlindexer
 - add support for Cc: Bcc: Message-ID:
In-Reply-To: References: From: and To:
 - add exclude and include filters to strigicmd
create and update commands
 - add deindex option, it can be used for removing
dirs or files from an index
   created by strigi

0.3.11
 - SunOS, BSD, 64 bit and Coverity compatibility
fixes
 - Search in a set of default fields and not just
in the text content of a file, if no specific
field is specified.
 - Add histogram widget to simple search client
 - Add support for Ogg Vorbis
 - Better decoding of email headers
 - Expand Query object to handle nested queryies
 - Fix highlighting and display of title in search
results.
 - Fix path for the child indexables
 - Fix memory problems in archivereader
 - Check for too short file names and omit the RPM
trailer from the results.
 - Add an additional unit test for the RPM stream
provider.
 - Revert raise() to kill(getpid()) because raise
hangs the thread.
 - Install qtdbus library for strigi.

0.3.10
 - Convienience classes for using Strigi over Qt
4.2 DBus
 - Change buildsystem to allow building of
deepfind, deepgrep and xmlindexer
   separately
 - Speedup of deepfind by selectively using only
the analyzers deepfind needs
 - Many portability fixes (GCC 3, Forte, MSVC)
 - New, more efficien plugin loading
 - Add IFilter plugin for the Windows version
 - Remove the big Strigi lock (faster indexing)
 - Switch strigiclient to communicate of DBus
instead of over a unix socket
 - Reorganization of the indexer with a new
IndexerConfiguration
 - Improvements of file name filters
 - New Qt widget for configuring file name filters
 - Add file name setting to the DBus interface
 - Move verbose unit tests
 - Bugfixes in some streams

0.3.9
 - Added deepfind and deepgrep, programs that are
enhanced versions of find
   and grep.
 - Added a new way of storing the configuration in
an xml file.
 - Added a way to search in multiple indexes.
 - Added xmlindexer, a program that outputs the
file parsing results as xml.
   This is convenient for debugging and can also
used by other programs that
   do not want to write their own indexer. It
makes the superior Strigi
   indexer available to other software in a
convenient way.
 - More versatile filters that determine which
files to index. (Flavio
   Castelli)
 - Add possibility to index files from the client
by feeding the file into the
   daemon. This opens the way to indexing email
from remote servers and web
   pages.
