@ -44,8 +44,7 @@ A filter string consists of one or more runs of filter operators that each look
* ''prefix'': tests whether a tiddlers title starts with the prefix specified in the operand
* ''limit'': limits the number of subresults to the integer specified in the operand
* ''tag'': tests whether a given tag is (`[tag[mytag]]`) or is not (`[!tag[mytag]]`) present on the tiddler
* ''field:{field}'': or
* ''{field}'': tests whether a tiddler field has a specified value (`[modifier[Jeremy]]` or `[field:modifier[Jeremy]]`) or not (`[!modifier[Jeremy]]`)

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
