+ Searching large numbers of files for similarity can take significant cpu time. Part of this is the time to compute the similarity matrix for each file.\r
+ <para />\r
+ If the\r
+ <link linkend="PreferencesThumbnails">Cache Thumbnails</link>\r
+ option is selected in Preferences/General, the similarity matrix and the checksum will also be cached. This will reduce the time needed for future searches.\r
+ <note>If you frequently search on similarity and your images are in a tree arrangement under a single point, initiating a one-time search on similarity from the top of the tree will generate the similarity data for all images.</note>\r
+ <para>Similarity data are stored in a folder hierachy that mirrors the location of the source images. The data have the same name as the original appended by the file extension .sim.</para>\r

+ The root of the hierachy is:\r

+ <programlisting>$XDG_CACHE_HOME/geeqie/thumbnails/</programlisting>\r
