title: SQLite FTS4 snippet argument format
body: <p>I'm working on analyzing texts in RQDA and am using the Firefox SQLite Manager to access the database so that I can search files more easily. I've created and populated virtual table:</p>
  
  <pre><code>CREATE VIRTUAL TABLE texts USING fts4(filename, content)
  </code></pre>
  
  <p>Then I did a snippet search </p>
  
  <pre><code>SELECT snippet(texts, '_', '_', '...') FROM texts WHERE texts MATCH 'great OR Great'; 
  </code></pre>
  
  <p>This returns results where the snippet term is highlighted with an underscore.</p>
  
  <p>My questions:</p>
  
  <ol>
  <li>How do I implement the 6th argument (documentation) so to increase the snippet size? (I see a similar question on this but the response does not work.)</li>
  <li>How can I get the MATCH return to also show the filename for the snippet (first column in my table.) So the format will be "filename", "snippet".</li>
  </ol>
  
  <p>Thanks in advance for your help. </p>
