Can we put or in 2 regex conditions

Can we put or in 2 regex conditions?

If no, is there any alternative?

for example

index = idx1 | regex name = ^Aa or id = ^101

[mtranchita · Accepted solution]

If I follow your question it should just be a matter of crafting your expression properly
simple example:

index = idx1 | regex name="\w|\d"

Should return results where the value of the field called name is a word or digit character

Can we use upper function also to make the regular expression search case insensitive or is there any other way ?

Yes, you should be able to use any valid PCRE.
Splunk's documentation can explain this much better than I:
