I build a dynamic LFE file to jump to a location in the repository which has worked in the past on 10.2 desktop client.

<?xml version='1.0' encoding='Unicode'?> <laserfiche>
  <repository name ='SLOAPCDrepo'>
      <search phrase='{LF:Name="*", Type="F"} & {[]:[Site ID] = "1006"}'/>
  </repository>
</laserfiche>

Now I'm getting:

Error Code: 6000
Error Message: Error parsing 'C:\Users\rheitzman\AppData\Roaming\OIS10\OIS10\1.0.0.0\OIS_temp_LFE.lfe'
Unknown error. [6000:0xc00cee2c]

The search phrase works with the web client and when entered directly into the Search Syntax field for custom search in the desktop client.

What has changed in 10.3 that is causing this error?
