quite a few things that you do not want. On the other hand, email user
agents like Thunderbird usually store messages in hidden directories, and
you probably want this indexed. One possible solution is to have '.*' in
'skippedNames', and add things like '~/.thunderbird' '~/.evolution' to
'topdirs'. Not even the file names are indexed for patterns in this
list, see the 'noContentSuffixes' variable for an alternative approach
which indexes the file names. Can be redefined for any
subtree.
.TP
.BI "noContentSuffixes = "string
List of name endings (not necessarily dot-separated suffixes) for
which we don't try MIME type identification, and don't uncompress or
index content. Only the names will be indexed. This
complements the now obsoleted recoll_noindex list from the mimemap file,
which will go away in a future release (the move from mimemap to
recoll.conf allows editing the list through the GUI). This is different
from skippedNames because these are name ending matches only (not
wildcard patterns), and the file name itself gets indexed normally. This
can be redefined for subdirectories.
.TP
.BI "skippedPaths = "string
Paths we should not go into. Space-separated list of
wildcard expressions for filesystem paths. Can contain files and
directories. The database and configuration directories will
automatically be added. The expressions are matched using 'fnmatch(3)'
with the FNM_PATHNAME flag set by default. This means that '/' characters
must be matched explicitely. You can set 'skippedPathsFnmPathname' to 0
to disable the use of FNM_PATHNAME (meaning that '/*/dir3' will match
'/dir1/dir2/dir3'). The default value contains the usual mount point for
removable media to remind you that it is a bad idea to have Recoll work
on these (esp. with the monitor: media gets indexed on mount, all data
gets erased on unmount). Explicitely adding '/media/xxx' to the topdirs
will override this.

quite a few things that you do not want. On the other hand, email user
agents like Thunderbird usually store messages in hidden directories, and
you probably want this indexed. One possible solution is to have '.*' in
'skippedNames', and add things like '~/.thunderbird' '~/.evolution' to
'topdirs'. Not even the file names are indexed for patterns in this

- This may prevent detection of change in some marginal file rename cases

XAPIAN_FLUSH_THRESHOLD) documents, which gives little memory
usage control, as memory usage also depends on average document

<listitem><para>This variable defines the job input queues

queue depth for each stage (three integer values). If
a value of -1 is used for a given stage, no queue is
used, and the thread will go on performing the next
stage. In practise, deep queues have not been shown to
increase performance. A value of 0 for the first queue
tells &RCL; to perform autoconfiguration (no need for
the two other values in this case) - this is the
default configuration.</para>

<listitem><para>This defines the number of threads used
for each stage. If a value of -1 is used for one of

for the last stage because updating the &XAP; index is
necessarily single-threaded (and protected by a
mutex).</para>

<para>The following example would use three queues (of depth 2),

processing their text, and one to update the index. This was
tested to be the best configuration on the test system
(quadri-processor with multiple disks).
<programlisting>
thrQSizes = 2 2 2
thrTCounts = 4 2 1
</programlisting>
</para>
<para>The following example would use a single queue, and the
complete processing for each document would be performed by
a single thread (several documents will still be processed
in parallel in most cases). The threads will use mutual
exclusion when entering the index update stage. In practise
the performance would be close to the precedent case in
general, but worse in certain cases (e.g. a Zip archive
would be performed purely sequentially), so the previous
approach is preferred. YMMV... The 2 last values for
thrTCounts are ignored.
<programlisting>
thrQSizes = 2 -1 -1
thrTCounts = 6 1 1
