Known bugs in current version and older versions:

Bugs that are listed in an older version section are supposedly fixed in
later versions. Bugs listed in the topmost section may also exist in older
versions. 

Latest (1.6.2):

- 1.6 NEAR crashes: 1.6 has added NEAR searches. Unlike what recoll did
  with PHRASES, stemming expansion is performed on terms inside NEAR
  clauses (except if prevented by a capitalized entry of course). There is
  a bug in Xapian at least up to 0.9.9, where NEAR does not support
  multiple OR subclauses, as would result from a multiple expansion. This
  manifests itself by a 'not implemented' Xapian exception. Workarounds:

      - Prevent expansion of NEAR terms (possibly except one) by
        capitalizing them.

      - Or apply the following patch to xapian 0.9.9, inside the "api/"
        directory: 
         http://www.recoll.org/xapian/xapNearDistrib.patch
        or fetch the already patched source:
	 http://www.recoll.org/xapian/xapian-core-0.9.9-recollNEARpatch.tar.gz

        then recompile, and install.

  I hope that the fix will make it into xapian at some point.

- If you are seeing a delay of a few seconds before the result list
  displays for the first query of a recoll instance, try changing the
  result list font in the query preferences. This is not a recoll problem,
  I don't know the exact cause (I've seen it happen with "Sans Serif" and
  go away with Helvetica or Arial).

- When a mime type has an external viewer defined, but the actual file is
  compressed (ie: xxx.txt.gz), recoll will try to start the external viewer
  on the compressed file, which will not work in most cases.

- There are problems which have been reported indexing big mailstores
  (several hundreds of thousands of messages): resulting in a very big
  database and even crashes during indexation.

- Under some versions of KDE (ie: Fedora FC5 KDE 3.5.4-0.5.fc5), there is a
  problem with the window stacking order. Opening the "browse" file
  selection dialog from the advanced search dialog will stack the latter
  under the main window, possibly making it invisible. This is quite
  probably a Kwin bug, possibly related to 
  http://bugs.kde.org/show_bug.cgi?id=79183 or a correction thereof.

- Under Solaris, it is necessary to perform initial indexing with the
  recollindex program (the recoll index thread doesn't work for creating
  the database). Don't know the reason. Only idea I have is problem with
  exception handling (recoll catches an exception while trying the
  yest inexistant db).

***************************************************************************
1.5.10
- If a defaultcharset was set in the configuration file for a subdirectory,
  it would stay in effect for all subsequent files/directories (except if
  explicitely overridden), potentially causing many transcoding errors.

1.5.[1-7]
- Dates in result list come from the file's ctimes, which may be confusing
- Some rare MIME messages with null boundaries can crash the indexer.

1.5.0
- Under some conditions, recoll startup and exit could be very slow: the
  simple search history list had serious problems with non-ascii strings,
  whose size sometimes doubled at each program startup/stop.

1.3.3

- Several of the external filters did not handle path names with embedded
  spaces (rcluncomp rclsoff rclps rclmedia rcldjvu). This is fixed in 1.4.

- If your QT installation is built with the QT_NO_STL flag, Recoll will not
  compile. I have a patch for this (will be fixed in the next release),
  contact me if you get the problem. Typical error message:
     main.cpp:160: error: no match for 'operator+=' in 'msg += reason'

- The 'None of these words' field in the complex search does not work if
  there are no other filled fields (it transforms into an ordinary
  search). Workaround: enter very common term(s) in the 'any of these
  words' field.

- Indexing cannot currently be conveniently and cleanly stopped when it's
  started. You can kill the process, and keyboard interrupt might work, but
  this may leave the database in a bad state. This is fixed in the upcoming
  release, there is no current workaround.

1.2.2
- The preview window is supposed to scroll after loading the document so
  that the first search term is visible. This does not work in many cases.
- The result list title is not shown for sorted lists

Notes on older versions:
- Trouble compiling on some linux systems (Gentoo and Slackware?). There
  existed a quite common issue where the Recoll link will fail trying to
  use a libstdc++.la file. This was due to a problem with the xapian-config
  program. A workaround has been included in the configure script for
  recoll 1.2.2, and the problem should not occur any more.

- Case-insensitive search should now work in most cases (used to not work
  except for accented ascii).

- All directories and files with names beginning with a dot were ignored
  by the skippedNames directive in the default recoll.conf file from
  older versions (no indexation of mozilla or thunderbird email !). An
  upgrade will not fix this (it will not modify an existing
  configuration). You need to edit recoll.conf by hand and remove the .*
  from skippedNames.
