Dans le cas contraire, Kiwix va vous demander si vous voulez indexer le fichier ZIM ou non. Vous devrez confirmer si vous voulez utiliser le [[Special:MyLanguage/Features#Search_engine|moteur de recherche à plein texte]] ou annuler si vous voulez utilisez le programme sans cette fonctionnalité.
This step is very time-consuming. Depending on the size of your ZIM file and the speed of your computer, might last several hours or even several days for big packages like the English Wikipedia. Note that there is a 20 to 100 percents difference in size between the indexed and non- indexed ZIM files and if you want to index a ZIM file, your computer will have to create the index files which their size is equal to the same difference of the indexed and non- indexed ZIM files, so be careful to do this process without turning your system down or closing the application.
You can also see how many percents of the indexing process has been proceeded or remained in the progressive green bar on the Status bar (like [[File:Indexing-progress.png|link=]]), so your status bar should be active and do this appear that from '''Display''' menu if you can't see it now. Note that you won't need to do this long process if you download the Pre-Indexed ZIM file.
