Because I forgot to pay attention to the e-mail headers.... Sorry about that! Anyway, this one is solved.

Thanks Joe. Partly, was taking the example in the documentation a little too seriously (using "str"). Silly me. There is one other catch. I was passing in two words from the command line: "compare foods".
Using just "compare" by itself brought up the record. As long as I pass only one word of the field value I am searching for, it works. It breaks when I enter anything more.

With the commas between the two "english" words did not change much.
You need to give each unique element to be replaced a unique name, like

"""SELECT * FROM entity WHERE to_tsvector(%(lang)s,
entity_name) @@ to_tsquery(%(lang)s, %(term)s);"""
{'lang': "english", 'term': search_term}
I suggest you read about Python dictionaries as well.
Using just "compare" by itself brought up the record. As long as I pass only one word of the field value I am searching for, it works. It breaks when I enter anything more.
BUT... it *does* work. I probably should code an exception for when the user tries to type in more than one word at the prompt to catch that and offer them a second chance.
Thanks again!
Don
