Hello, folks.

I am undertaking keyword searches of chat logs.  The keywords are stored as 
themed lists in fields.

One of the things I am interested in is finding lines where one contributor 
asks another about where they live, shop, go to school etc etc.  So, (among 
other phrases) I filter for lines in the text containing the acronym “ asl ” 
(nowhere are quotes actually included in fields or variables, they’re just in 
this mail).  I pad with spaces so as not to find “asleep”.  I also want to find 

So I repeat through lines of the keyword field “location"

Filter lines of tsource with tpattern

…  which works for everything except fails to match “asl?”.  It occurred to me 
that perhaps the question mark is being interpreted as a regex symbol, so I 
tried changing the line in the field to read “ asl/?”, but that doesn’t find 
the “asl?” that I can see in the third line of the text to be searched….

What am I doing wrong?  Is this something to do with regex?

Oh yes, and I thought there might be invisible characters messing things up, so 
I exported source text as plain text from BBedit, with no improvement.

best wishes
