The DASL spec defines a like operator:
http://greenbytes.de/tech/webdav/draft-reschke-webdav-search-07.html#rfc.section.5.15

which however is not supported by Slide. You may want to use Slide's 
proprietary:
<D:where>
   <SLIDE:propcontains xmlns:SLIDE="http://jakarta.apache.org/slide/">
     <D:prop><D:displayname/></D:prop>
     <D:literal>.txt</D:literal>
   </SLIDE:propcontains>
</D:where>
