How to write a placeholder for letters in a search, filter or regexp

[Surya]

Hi,

I just don't remember anymore the englisch word for it or the word, which is used in TW for that- so I don't know, what to ask google for (I tried a lot of searches with placeholder, filter, regexp, and so. But didn't find, what I am looking for.

I want to build a filter with a word with a letter-placeholder at the beginning or the end. So that the filter finds "fo", but also "foo" and "fold" and " "a folded".

Can you please help?

Thanks!

Surya

Wildcard? With regular expressions, it is the dot "." to match a single character and a dot+star ".*" to match zero or more characters.

Here is a good regexp reference site (that I likely read about on this forum).

I hope that is what you were looking for.

Hi

What you're talking about could be the prefix (and suffix) operators in filters.

Hi Michael and Sycom,

yes, that was it, what I have been looking for- wildcard!

(Not the prefix & suffix).

Thanks for helping!
