I have an application where in dictated results, the string "***" is put in to indicate that a dictated word can not be understood. I have a text field containing the output of the dictation, and when I look at the string I see the *** in the data.
However, I have been unable to search/filter for the string *** in the discover tool or with TSVB.
If I use *** as a filter string, it gets treated as three wildcards and anything with more than 3 tokens is returned (didn't spend a lot of time on that, so maybe I am not interpreting the results correctly)
If I use quotes
"***", I get no results.
If I use backslash escaping
\*\*\* I get no results.
If I use slash escaping
/*/*/* I get no results.
Is this an issue with the analyzer used in processing the field? Or is it a problem getting the wildcard character escaped?
