The search box keeps only word characters, but FTS5 still reads AND, OR, NOT and NEAR in the query as operators, so searching for "AND" or for "salt AND" raised "fts5: syntax error" and answered with a 500. Quoting each word makes FTS5 look for it as text, which is how it already treats the same words in lower case.
