Search operator: search for whole words only

[Hubert]

Hi,

I want to only find whole words when using the search Operator.

I've tried the options listed here but cannot make my filter expression match whole words only, even when using the literal flag for search strings.

For example, when the search string is TW I only want to find this:

• TW info
• Hints for tw linking

and NOT this:

• Two little monkeys
  

I suspect that the whole word search can be achieved with regex, would anyone have any idea how?

Many thanks!

Something like:

[regexp:text[\bTW\b]]

Thanks Mark.

I still can't get it to work. Here's my entire filter expression. I know it's clearly incorrect but I can't find any other way to reconcile the different types of brackets with the title flag, the regex expression and the in-filter transclusion.

My search string to be matched is in the note field of the $:/note tiddler:

<$list filter="""[tag[note]regexp:title[\b{$:/note!!note}\b]]""">

</$list>

Thanks!

OK, I had to resort to the $wikify widget but now it works:

<$wikify name="searchterm" text="""\b{{$:/note!!note}}\b""">
<$list filter="""[tag[note]search:title:regexp<searchterm>]""">
<<ListedNotes>>
</$list>
</$wikify>

Thanks again Mark for pointing me in the right direction!

Regards,

Hubert

For the record, \b appears limited to ASCII characters. It will not match non-English diacritics correctly, as explained in this post.
