Xapian have support for wildcard search
wild* matches wild, wildcard, wildcat, wilderness
but it need to be enabled by passing a specific flag to the query
parser, this is very useful for forum search so enable it in addition
to default Xapian search capabilities
Add FLAC standalone indexer
Add indexing common music tags for all formats supported by taglib
File indexer reindex files that have been indexed by older versions of
the indexer and reindex them
Sparse improvements to deep indexing
ATM it support extracting metadata only from OGG files.
The system has been designed to be easly extensible to more file formats
registering more indexer functions which just need to extract metadata
from a certain type of file and feed it to Xapian.
The system has been integrated into existent file search system to
through generric search requests and results, it keep a good level of
retro-compatibility due to some tricks.
The indexing system is released under AGPLv3 so when libretroshare is compiled
with deep search enabled AGPLv3 must be honored instead of LGPLv3-or-later.
Cleaned up the debian copyright file using non-deprecated license
code-names.
Avoid problems to serialization on different platforms, without breaking
nested STL containers serialization.
The conversion have been made with sed, and checked with grep, plus
kdiff3 visual ispection, plus rutime tests, so it should be fine.
Some modifications breaks retrocompatibility of GXS search:
remove horrible templated RsTypeSerializer::serial_process for
RsGxsGroupSummary with hardcoded member names
RsGxsGroupSummary doesn't use old TLV serialization format anymore
RsGxsGroupSummary remove unused description member
RsGxsGroupSummary derive from RsSerializable and use serialization
helper macro
Add autor id and signature flags to the index so there is no need to
retrive them from GXS, thus improving performances
RsGroupNetworkStats initialize members properly
RsGxsGroupSummary rename members to follow usual mMemberName convention
