How to escape special characters in a KQL query?

Question

In a list I have a column with these values:

MyField
-------
foo.A
foo.B
foo.*

I want to search for these values. I've plumbed all managed properties and crawled content.

• If I search myfield:"foo.", all results are returned ==> Expected
• If I search myfield:"foo.A", results with the foo.A are returned.==> Expected
• If I search myfield:"foo.*", both foo.A and foo.B are returned, but not foo.* ==> not Expected. I need to get only foo.*

How to search for literal *?

I also tried : myfield:"foo.\*", myfield:"\foo.*", myfield:{"foo.*"}, but none worked.

Documentation does not mention any way to escape special characters.

Answer 1

KQL is also used when doing compliance searches in Microsoft Exchange.

I was able to use `$ to escape characters when doing searches in Exchange

"foo`$*"

Answer 2

I was able to do it with just ` in Kibana logs with KQL syntax
