and directory names. Have a look at the default
configuration for the initial value, some entries
may not suit your situation. The easiest way to
see it is through the GUI Index configuration
"local parameters" panel. The list in the default
configuration does not exclude hidden directories
(names beginning with a dot), which means that it
may index 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.</p>

<p>Absolute paths we should not go into.
Space-separated list of wildcard expressions for
absolute filesystem paths. Must be defined at the
absolute filesystem paths (for files or
directories). The variable must be defined at the
top level of the configuration file, not in a
subsection. 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 explicitly. 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). Explicitly adding '/media/xxx' to
the 'topdirs' variable will override this.</p>

<p>Decide if we store the documents' text content

The last Xapian index format with good

<p>Newer Xapian index formats have rendered our
use of positions list unacceptably slow in some
cases. The last Xapian index format with good
performance for the old method is Chert, which is
default for 1.2, still supported but not default
in 1.4 and will be dropped in 1.6. The stored
document text is translated from its original
format to UTF-8 plain text, but not stripped of
upper-case, diacritics, or punctuation signs.
Storing it increases the index size by 10-20%
typically, but also allows for nicer snippets, so
it may be worth enabling it even if not strictly
needed for performance if you can afford the
space. The variable only has an effect when
creating an index, meaning that the xapiandb
directory must not exist yet. Its exact effect
depends on the Xapian version. For Xapian 1.4, if
the variable is set to 0, the Chert format will
be used, and the text will not be stored. If the
variable is 1, Glass will be used, and the text
stored. For Xapian 1.2, and for versions after
1.5 and newer, the index format is always the
default, but the variable controls if the text is
stored or not, and the abstract generation
method. With Xapian 1.5 and later, and the
variable set to 0, abstract generation may be
very slow, but this setting may still be useful
