Installing over an older version and other notes

1.20-26 indexes are fully backward compatible. Installing 1.26 over an 1.19 index is possible, but there have been small changes in the way compound words (e.g. email addresses) are indexed, so it will be best to reset the index. Still, in a pinch, 1.26 search can mostly use an 1.19 index.

New index format with Xapian 1.4: the default on-disk format of Xapian 1.4 (glass) has changed to improve the performance of phrase searches. This had the infortunate consequence of rendering the Recoll snippets generation method excessively slow except for very small indexes. In consequence, new indexes created by Recoll 1.24/26 using Xapian 1.4 have a different format and store the document texts inside the index. No specific action is required from the user, except if you have and old index and want to use the new format (nicer snippets, faster phrase searches), in which case you should delete the old index (see next).

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/[me]/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 1.27

  • Partial support for external term generators. In practise this allows using language-sensitive text analysers (Mecab-ko directly and others through konlpy) for indexing Korean text. See the page about Korean text in english and in korean.

  • Index MS-Word .docx endnotes and footnotes.

  • GUI: Fix having to type CR twice for multi-word searches.

  • Do not ignore white space while splitting CJK text with the n-gram splitter.

  • Windows: the Recoll Python extension is now available. This makes it possible to run the Recoll WEBUI under Windows.

  • Windows: MSVC build. This allows building the Python extension module (the official Python distribution for Windows is built with MSVC, so I did not find a way for the MinGW-built Recoll extension to work).

  • Windows: fix "special indexing" feature which had trouble passing arguments to recollindex.

  • Windows: fix bug which prevented Recoll from initializing when the configuration directory was inside the user’s home and the user login was not ASCII.

  • Windows: improve processing of non-ASCII paths in a few other places.

Minor releases at a glance

  • 1.27.2

    • GUI: saving/restoring simple searches: the list of active external indexes is now restored with the query. Just open the external indexes preferences page to reset it when you are done.
