wildcard query question

[Alessandro Senserini <al...@plateau.com>]

I have indexed a field called courseTitle of 'text' type (as in the
schema.xml but without the stemming factory) that contains

 

COBOL: Data Structure

 

Searching with a wildcard query like

 

courseTitle:cobol\:*  AND courseTitle:data* AND courseTitle:structure*

 

(the colon character ":" is escaped) the record is not found.  If the
search is

 

courseTitle:cobol*  AND courseTitle:data* AND courseTitle:structure*

 

the record is found.  I was wondering how the colon character affects
the search, and if there is another way to write a wildcard query.

 

Thanks.

most likely the issue is that your analyzer is striping out the colon 
character, hence your normal phrase search works (because the colon is 
striped out both when indexing and querying) but your wildcards don't, 
because the wildcard query string is not analyzed...
