You can use the FTS 5 Query syntax for searching. Full search will look in the name and content columns. Title search will limit the search to the name column. Note: a colon has a special meaning in FTS5, if you want to search for a string containing colons, make sure to put the string in double quotes. You can see an error message reporting a "no such column" when using colons in an unquoted search string.
