Comment Property Problem

Dear All,
  I am using slide2.2. I am using
lucene.LucenePropertyIndexer. I have configured to index a
custom property i.e. "comment". It gets
successfully indexed and comes in DASL result. But other
custom properties like
"author","city" does not get indexed
and does not comes in DASL result. DASL gives prop not found
in respose. What is going on? Can somebody tell me?
  Thanks...
