ComplexPhraseQueryParser/Enumerating Wildcard Queries

[GoogleCodeExporter]

We are troubleshooting performance issues related to wildcard queries 
running against the ComplexPhraseQueryParser (introduced in Lucene 3.0). 
Some wildcard queries like "quality operations providing quality food 
services job requirements: click here to apply for this job*" require a 
maxClauseCount > 40K to match against the DBSight implementation that 
we're using (and run longer than 2 seconds too).

We'd like to understand what the 40K clauses are as we don't think we have 
nearly that many unique words that have job* as a prefix. 

Can Luke support the ComplexPhraseQueryParser or otherwise show the fully 
enumerated query for wildcard searches?
