[TW5] Find exact match

[Jon]

Hi,

I want to search for an exact text match (eg "Unique text"). I've come across this [!is[system]regexp:text[Unique text]] but it doesn't quite work.

For instance it will also find "que text".

What would do the job?

Thanks
Jon

Can you confirm this behaviour for tiddlywiki.com

I tested this at tiddlywiki.com and it seems to work ok. Which TW <<version>> do you use?

{{{[!is[system]regexp:text[Unique text]]}}}

Hi Jon

If you want to check for a precise match with the content of a field you can use the "field" filter operator:

[!is[system]text[Unique text]]

It's also possible to fix the regexp version by anchoring the text to the start and end of the text:

 [!is[system]regexp:text[^Unique text$]]

Best wishes

Jeremy.

Hi,

thanks for the replies, but I can't seem to get the desired results.

Using the Advanced search at Tiddlywiki.com and typing the following expressions into the box will produces these results:

[!is[system]regexp:text[feel chained]] will match to tiddler "HelloThere"

but so will

[!is[system]regexp:text[chained]]

Whereas

[!is[system]regexp:text[^feel chained$]] produces 0 match

[!is[system]text[feel chained]] produces 0 match

and

[!is[system]regexp:text[^$]] produces the following matches

Caruso - Ave Maria

I must be doing something wrong, but can't quite see what.

Thanks

Jon

Hi Jon

I'm afraid I misunderstood. I thought you were trying to match tiddlers whose entire body text was an exact match.

If you're trying to perform an exact match of a substring then I'd expect this to work:

[!is[system]regexp:text[feel chained]]

It's not a great solution, because regexp special characters will be treated differently - for example, matching a period will actually match any character, not just a period.

Best wishes

Jeremy.

Hi Jeremy,

I should have explained what I'm trying to do.

I want to filter a number of tiddlers so I can apply tags to them as a batch.

Each of the tiddlers contains a line of text which I can use as an exact match

The problem with

[!is[system]regexp:text[feel chained]]

is that it will also match

[!is[system]regexp:text[chained]]

and so will also match to a tiddler with "chained" in the text (as well as "feel chained")

and so applying the filter to my case would include additional results which I don't want to tag.

Regards

Sorry, I've just realised my stupidity!

[!is[system]regexp:text[feel chained]]

does exactly what it says on the tin!

Thanks

Jon
