If the FTS table is an FTS4 table (not FTS3), a token may also be prefixed
with a "^" character. In this case, in order to match the token must
appear as the very first token in any column of the matching row. Examples:
</ul>
<codeblock>
<i>-- All documents for which "linux" is the first token of at least one</i>
<i>-- column.</i>
SELECT * FROM docs WHERE docs MATCH '^linux';
<i>-- All documents for which the first token in column "title" begins with "lin".</i>
SELECT * FROM docs WHERE body MATCH 'title: ^lin*';
</codeblock>
