[opencms-dev] Customise search ERROR [OpenCMS 6.0] (resend)

[David]

 Hi,
 I am trying to customise the search behaviour in OpenCMS such that to allow 
an application to dynamically create a new index source and search index 
from an arbitrary set of files in VFS and perform a search on those files. 
The code that I am using is given below. When I run this from a JSP page it 
returned with an error saying *No analyzer found for language "null". *The 
trace log for this error is given at the bottom which points to method 
getAnalyzer() in CmsSearchManager. So I checked the source code of this 
method and it looks perfectly normal given that I already set the locale for 
my CmsSearchIndex object to 'en'. I even test printing out the analyzer 
class name (see code) using getAnalyzers() method of the CmsSearchManager to 
make sure that analyzer for 'en' locale exists. 
 So the analyzer is there and the locale has been set for the CmsSearchIndex 
object, why does it still complain about the analyzer being not found and 
weird enough in the error message it seems not able to detect the locale 
("null" value)? Has anyone experienced this before and perhaps could provide 
some insights? Thanks very much for your prompt response.
 Rgds,
David.
