FullText Index Search Problem

Hi Everybody,

I have a database contains more than 10000 documents and its full text Indexed.

In that I have a text field called(DOCNUMBER).

Content of the DOCNUMBER would be like this

ZA01-****

ZA02-****

The problem is when I give a search in a view

I am not getting the proper count

Actual count of ZA* = 1500

Query 1)

([DOCNUMBER] contains (ZA*))

Result 780

Query 2)

([DOCNUMBER] contains (ZA00*))

OR ([DOCNUMBER] contains (ZA01*))

OR ([DOCNUMBER] contains (ZA02*))

OR ([DOCNUMBER] contains (ZA03*))

OR ([DOCNUMBER] contains (ZA04*))

OR ([DOCNUMBER] contains (ZA05*))

Result 1500

Why the search is not working when I give ZA* ?

Thanks in Advance

Joseph
