hi to all,

I am using the webadmin 1.0
the database is created and filled in java.
while using index in rest as below:

$ curl -H Accept:application/json http://localhost:9999/index/node/rootnodelabelindex/Products

I got this error:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 org.apache.lucene.index.CorruptIndexException: Incompatible format version: 2 expected 1 or lower</title>
</head>
<body><h2>HTTP ERROR 500</h2>
