<p>Generate a snippet. </p>
<p>This method selects a continuous run of words of less than about <em>length</em> bytes from <em>text</em>, based mainly on where the query matches (currently terms, exact phrases and wildcards are taken into account), but also on the non-query terms in the text.</p>
<p>The returned text can be escaped (by default, it is escaped to make it suitable for use in HTML), and matches with the query will be highlighted using <em>hi_start</em> and <em>hi_end</em>.</p>
<p>If the snippet seems to start or end mid-sentence, then <em>omit</em> is prepended or append (respectively) to indicate this.</p>
<p>The stemmer used to build the query should be specified in <em>stemmer</em>.</p>
<p>And <em>flags</em> contains flags controlling behaviour.</p>
<p>Added in 1.3.5. </p>
