Words match in digiKam search
 
|
Hello, I have some questions about the way digiKam performs strings comparisons when searching for keywords. 1. The digiKam handbook says "searches are case insensitive". Well, doesn't seem to be the case in my environment (digiKam 1.2.0, Linux OpenSuSE 11.3 with KDE 4) with non US ASCII characters. I have several pictures with captions containing the word "église" (for non French readers, église is a church). E.g. picture 1 is titled "Petite église rouge", and picture 2 is titled "Église à vendre". (With an uppercase É because all my titles are capitalised.) Now, if I type (in the words search input field) the word "église", I get picture 1 but not picture 2. And if I type "Église", I get picture 2 but not picture 1. Clearly a case sensitive match, concerning only the ISO Latin characters (typing "éGLISE" finds picture 1 too, and "ÉGLISE" finds picture 2). I suspect it could be a problem with non ASCII characters encoding. My desktop environment is set to French, ISO-8859-1 charset. How digiKam internally encodes its text strings ? UTF-8 maybe ? This could possibly explain a mismatch. Has anyone already seen such an issue, and what could be the best way to walk around ? Is there a way to tell digiKam about user input encoding, us-ascii, iso-8859-x, utf-8 ? Or is it shadowed by the X11/Qt/KDE layers ? 2. Another question related to strings match, just because I'm curious :-) In the digiKam configuration window, folder "Miscellaneous", there's a configuration parameter named "String comparison type", with a selection menu proposing two options, Natural or Normal. I couldn't find anything about that in the handbook. What is a "Normal" comparison type, and a "Natural" comparison type ? Thanks in advance, Jean-François _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

There no "What's This" assigned to this widget". And the menu comparison options menu, Natural vs. Normal, has a tooltip but not very readable. Tooltip text starts with "Sets the way in which strings are compared inside digiKam, etc.", but seems to be a long text and I can't have it displayed correctly. I can see that text embeds some XHTML formating, e.g. "<br/>" to trig a line break. And this markups are juste displayed as raw text, not processed, so the whole tooltip text appears on one long line, truncated at the right edge of my screen. But this was just a matter of curiousness. My major problem is the case insensitive search when words contains non US-ASCII characters. Could be a problem with my graphic interface setup, or not. Could non english writers digiKam users confirm - or not - that case insensitive search works well with their country charset ? If yes, I'll investigate in my X11/Qt/KDE configuration. If not, I'll just do my searches twice, typing the lowercase version then uppercase version of words containing Latin1 characters :-) Thanks in advance, Jean-François _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Hi Jean-François,
Here you find the tooltip tekst as displayed in my dk 2.1.0 http://dl.dropbox.com/u/30489651/Schermafdruk-8.png Regards, Rinus Op 28-08-11 21:33, Jean-François Rabasse schreef:

Very interesting. So this should show my problem is outside digiKam comparison code. Anyway I suspect an insane mixture of ISO encoding and Unicode. Metadata stored in images files by digiKam (at least the ones with keywords, xmp.dc.description and xmp.digikam.tagslist) seems to be UTF-8 encoded. It's probably the same in the digikam.db, and my keybord inputs are ISO Latin ! Investigation in progress... :) Thanks for all, Jean-François _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

What your keyboard produces should be highly configurable those days sysyem->preferences->keyboard and beyond that there is more like xbindkeys but that's complicated I think may be of no use to you but have a look here: /home/jansen/Bureaublad/Schermafdruk-10.png Rinus

May be a problem of the used string-compare library? digikam --version: Qt: 4.7.3 KDE Development Platform: 4.7.1 (4.7.1) digiKam: 2.0.0 Greetings, Günter _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
