<p>^(For example, a query like the following might be used to find all
R*Tree entries that overlap with a circle centered a 45.3,22.9 with a
radius of 5.0:
<codeblock>
SELECT id FROM demo_index WHERE id MATCH circle(45.3, 22.9, 5.0)
</blockquote></pre>)^
<p>^The SQL syntax for custom queries is the same regardless of which
interface, sqlite3_rtree_geometry_callback() or sqlite3_rtree_query_callback(),
is used to register the SQL function. However, the newer query-style
callbacks give the application greater control over how the query proceeds.
