  <div class="markdown level0 remarks"><p>A hint does not change the value of the expression it is applied to,
it only tells LiveLinq to create and use an index on that property, if possible.</p>
<p><b>Note: </b>Hints can only be used in indexed queries (with <b>AsIndexed()</b> extension method).
Using them in live views (with <b>AsLive()</b> extension method) will result in an exception.</p>
See <span style="C1H Jump">How to create indexes</span>.
