file1.group.insert(&quot;ug1&quot;);<br>file1.group.insert(&quot;ug2&quot;);<br>file1.group.insert(&quot;ug3&quot;);<br><br><a href="http://file2.name">file2.name</a> = &quot;file2&quot;;<br>file2.group.insert(&quot;ug2&quot;);<br>

<br><a href="http://file3.name">file3.name</a> = &quot;file3&quot;;<br>
file3.group.insert(&quot;ug3&quot;);<br><br><br>and i need search by file name or group, and  file name should can be support <span class="web-item">fuzzy search (eg. *ile , *1 ....)<br></span>can boost mutil index do this,if can ,what kind index need?<br>
