+FILTERING A QUICKFIX OR LOCATION LIST:
+				    *cfilter-plugin* *:Cfilter* *:Lfilter*
+If you have too many entries in a quickfix list, you can use the cfilter
+plugin to reduce the number of entries.  Load the plugin with: >
+
+    packadd cfilter
+
+Then you can use the following commands to filter a quickfix/location list: >
+
+    :Cfilter[!] /{pat}/
+    :Lfilter[!] /{pat}/
+
+The |:Cfilter| command creates a new quickfix list from the entries matching
+{pat} in the current quickfix list. {pat} is a Vim |regular-expression|
+pattern. Both the file name and the text of the entries are matched against
+{pat}. If the optional ! is supplied, then the entries not matching {pat} are
+used. The pattern can be optionally enclosed using one of the following
+characters: ', ", /. If the pattern is empty, then the last used search
+pattern is used.
+
+The |:Lfilter| command does the same as |:Cfilter| but operates on the current
+location list.
