I opened a HI ticket about this and it was communicated that the global text search does not respect more non-alphanumeric characters.
So it turns out that the keyword search doesn't respect
Meaning if you search for "
this_custom_word" and you expect to find
results, if one of those words is on the Stop list tables
ts_stop). It may not show up.
Just something HI made me aware of. I askd if they have other
delimiters, but they said its just
_ and space.
If I get more information I'll update this.
