zero termfreq for some search strings with special characters

[SK R]

Hi,
   I'm using standard tokenizer for both indexing and searching
process.Myindexed value is like "emp-id Aq234 kaith creating document
for search".
   I can get search results for the query CONTENT:"emp-id" by using hits =
indexSearcher.search(*query*).
   But if I try to get termfrequency of that term (CONTENT:"emp-id") by
using indexreader.termdocs(new Term("CONTENT","emp-id")).freq() , 0 results
returned.
   I think because of the analyzer I can get result in 1st case but absence
of analyzer I can't get result in 2nd case (term freq). Is it right?
   How do i get correct term frequency for that term?


Thanks & Regards
