I've been doing some testing with the v2.1 distribution and with the
updated one from subversion.

I used Gast to create one set of records, then imported 5 FGDC metadata
records for which I know the search results (these are the 5 records
included with the Isite distribution).

I could search the collection successfully via local search in the web
GUI interface.  Both full text search on the word "water" and a title
search on the same word yielded the expected results (6 hits for
AnyText="water", 1 hit for Title="water").

I then used the included CSW client (v 2.0.1) to do the same search.
Both GetCapabilities and DescribeRecord worked correctly using GET.
However, GetRecords failed in all cases.  Using CQL to send the query
term "water" for AnyText via POST yielded 0 hits (it should have had 6).
 Using Filter to send the same query gave an exception:

Using Z39.50 to submit the search did not succeed.  Below, I illustrate
using the Isite zclient command-line client program:

1.  Search for "water" in AnyText (use attribute 1016), request Full
records in XML.  The result was:

1.  Search for "water" in Title (use attribute 4), request Full records
in XML.  The result was:

> zclient, Version 2.2.3-SUSE92, Release 2005040603

There are exceptions noted ("String index out of range: -1") in the GN log.
