 ## Aging
 
-he rank of directories maintained by z undergoes aging based on a sim-ple formula. The rank of each entry is incremented  every  time  it  is accessed.  When the sum of ranks is over 5000 (`$_ZL_MAXAGE`), all ranks are multiplied by 0.9. Entries with a rank lower than 1 are forgotten.

 ## Frecency
        
-Frecency is a portmanteau of 'recent' and 'frequency'. It is a weighted rank  that depends on how often and how recently something occurred. As far as I know, Mozilla came up with the term.

 ## Matching
 
 z.lua has two different matching methods: 0 for default, 1 for enhanced:

 ### Default matching
 
 By default, z.lua uses default matching method similar to the original z.sh. Paths must be match all of the regexes in order.
