"Filter: Upper case and Lower case"
asn4293
New Altair Community Member
I find it very awkward that we have filter operator and we can only do it by having exact upper and lower case. I don't know but @IngoRM it should have been in the some options of filtering please. Also, if it is not in the software you should have it in, in the next update

hello @asn4293 so the Filter Examples operator does distinguish between lower and upper case on purpose. Lots of good reasons for it but it's an interesting suggestion to have a checkbox saying "ignore cases". Feel free to put it in our Product Ideas section.
Meanwhile if you want to use Filter Examples irrespective of case, I'd suggest using a RegEx expression or converting your text to one case using the Transform Cases operator (Text Processing extension).

Hi @asn4293,
Filter Examples can filter independently of the case. you can just choose expression and write something like:
lower(attribute) != "myvalue"

Dear@mschmitz,
Thank you so very much for support this would do the work. but it would be wonderful if this data set can also filter in between text for example "English" filter "glis" and we find it as english.

Hi,
sure. you would just use
.+glis.+
as a regular expression.
