 - an expression whith wild card supporting the shell expansion, the default
 - a regular expression, using the flag -re
 
-The only thing that needs to be remembered is to wrap in double quote the regular expression in conjunction with the **-re** flag 
-when you choose to use it, for example:
-
 ```
-vfind ~/nerd_tree/ -re "(.*)rem(.*)"
+vfind ~/nerd_tree/ -re '(.*)rem(.*)'
 ```
 
 all items matching the pattern are show in the result tree: in this specific case any name containing **rem** substring<br />
 The same results above can be achieved using the command version with the shell expansion:
 
 ```
-vfind ~/nerd_tree/ *rem*
+vfind ~/nerd_tree/ '*rem*'
 ```
 
 You can use as pattern any valid regular expression, for example pattern as this
 
 ```
-vfind ~/nerd_tree/ -re "(.*)rem|tree(.*)"
+vfind ~/nerd_tree/ -re '(.*)rem|tree(.*)'
 ```
 
 The folder matching the pattern are show collapsed with information about the total number of files and the size of the subtree.
 If you want to show the subtree expanded you can use the flag **-s**
 
 ```
-vfind ~/nerd_tree/ -re "(.*)rem(.*)" -s
+vfind ~/nerd_tree/ -re '(.*)rem(.*)' -s
 ```
 
 ## Include/Exclude path
 
 You can include a set of results selecting specific branch (or paths) with the option **-i** (include).
-For example:
+In this case the match is made exactly on the pattern provided, for example:
 
 ```
-vfind ~/nerd_tree/ -re "(.*)py" -i src
+vfind ~/nerd_tree/ -re '(.*)py' -i src
 ```
 
 include the results that along the path have the name **src**.<br />
 **NOTE** the command above is equivalent to 
 
 ```
-vfind ~/nerd_tree/ *py -i src             
+vfind ~/nerd_tree/ '*py' -i src             
 ```
 
-You can include the -i more than once, for example:
+You can include the -i more than once as in this case:
 
 ```
-vfind ~/nerd_tree/ -re "([0-9][0-9])|(^tree_(.*))" -i src -i .git
+vfind ~/nerd_tree/ -re '([0-9][0-9])|(^tree_(.*))' -i src -i .git
 ```
 
 the above command will search for files or folders with a **two digits** name or with the name beginning with **tree_**
 only in the path ***src*** or ***.git***
 
 
-In a similar manner you can exclude paths with the option **-e**, too in this case you can specify more than once the option -e 
+In a similar manner you can exclude from the results tree paths or items with the option **-e**.

+> The **-e** option can be any valid pattern that support the shell expansion
+
+too in this case you can specify more than once the option -e 
 
 ```
-vfind ~/nerd_tree/ -re "(.*)py" -e src
+vfind ~/nerd_tree/ -re '(.*)py' -e src
