 If a filter operator is written with curly brackets around the operand then it is taken to be a TextReference to the actual value. For example:
 
-''[search{$:/temp/search}]'': selects all tiddlers containing the string contained in the tiddler titled ''$:/temp/search''.
+* `[search{$:/temp/search}]`: selects all tiddlers containing the string contained in the tiddler titled ''$:/temp/search''.
 
 ! Regular Expression Filters
 
-The field-filter also accepts regular expressions in the form `/regexp/(modifier)`. Please refer to you favourite JavaScript documentation to learn more about regular expressions and modifiers.
+The ''field'' filter also accepts [[regular expressions|http://en.wikipedia.org/wiki/Regular_expression]] with the syntax `/regexp/(modifier)`. For example:
 
-In the easiest form, regular expressions allow you do do a search on substrings for every field:
-
-* `field:title/example/`: searches for all tiddlers having "example" in its title.
-* `field:title:/example$/`: `$` is an "anchor" for the end of the text. So "example" has to be the end of the title.
-* `field:text/jeremy|ruston/(i)`: Searches for tiddlers containing Jeremy's first or last name, ignoring the case.
+* `[field:title/example/]`: searches for all tiddlers having "example" in their title
+* `[field:title:/example$/]`: `$` is an "anchor" for the end of the text so that "example" has to be at the end of the title
+* `[field:text/summer|winter/(i)]`: Searches for tiddlers containing "summer" or "winter", ignoring case
