Installing over an older version and other notes
|
Note
|
Ubuntu commands installed as snap packages can’t create arbitrary files under /tmp. This is
for example the case by default for pdftk which is used by Recoll to extract PDF attachments. For
best results, set TMPDIR to a location which belongs to you (e.g. inside your home, with something
like export TMPDIR=~/tmp in your shell startup script). Recoll could conceivably work around the
problem all by itself, but I find it in bad taste to create temporary files in an arbitrary location
inside your home.

1.20 to 1.41 indexes are fully backward compatible. No need to reindex when upgrading.
Always reset the index if you do not know by which version it was created (e.g.: you’re not sure
it’s at least 1.18). The best method is to quit all Recoll programs and delete the index directory
(rm -rf ~/.recoll/xapiandb), then start recoll or recollindex.
recollindex -z will do the same in most, but not all, cases. It’s better to use the rm method,
which will also ensure that no debris from older releases remain (e.g.: old stemming files which are
not used any more).
On Windows, the index is located by default in C:/Users/[yourlogin]/AppData/Local/Recoll/xapiandb
Case/diacritics sensitivity is off by default. It can be turned on only by editing recoll.conf ( see the manual). If you do so, you must then reset the index.
Changes in Recoll 1.41.0
-
Tibetan support: previous versions processed Tibetan all wrong. We now use n-grams.
-
The Mac OS bundle now uses libmagic and multithreading for much better indexing performance. This is a just a build procedure change.
-
Small changes to help the AppImage find external helpers.
