Ignoring Case on field values

[DotTest37]

Im extracting values on a field with this Reg ex:

<technology[^>]*>(?P<Technology>[^<]+)

It returns different values when uppercase and lowercase,, for example:
Audio
AUDIO
audio

How can I make it ignore the Case?
Thanks guys!!

Splunk is not case sensitive when it comes to field values so we can extract fields with mixed case and not worry about searching.
In other words, these searches would all return the same results:

technology=Audio
technology=AUDIO
technology=audio

NB: Fields are case sensitive, but the values are not. So these searches would NOT return the same result:

Technology=audio
TECHNOLOGY=audio
technology=audio

For reporting purposes, you may wish to show a consistent value. In this case, we can use the lower() or upper() functions of eval.

This will return audio

technology=AUDIO | eval technology=lower(technology)

This will return Audio

... | eval technology = if(len(technology)>0,upper(substr(technology,1,1)) + lower(substr(technology,2,len(technology))),technology)

You can have your regex ignore case with "(?i)" at the beginning of the line.

If your question is about how to have the value normalized to one value, try:

 ... | eval Technology=lower(Technology)
