The reason the wildcard is being dropped is because you have wrapped it
in a phrase query. Wildcards are not supported in Pharse Queries. At
least not in any Analyzers that I'm aware of.
A really good tool to see the transformations that happen to a query is
Luke, open it up against your index, go into the search section, choose
the analyzer you use and start playing around.
This has helped me countless times when creating I'm my own queries and
not getting the results that I expect.

I am sorry, just put the string to QueryParser.
But what make me confusing the code:
Query query = qp.parse("bbb:\"b*\" AND ccc:\"cc*\"");
doesn't work as i have expected. It drop the Wildcard *.

Thanks!
Now, I just use Query query = qp.parse("a*"); and meet the my
requirements.
Another question: how to parser query string like: title:"The
Right Way" AND text:go
please show me in java code. thanks.

Document<stored/uncompressed,indexed<field:abc>>
Document<stored/uncompressed,indexed<field:bcd>>
How can I get the first Document buy some query string like "a" , "ab" or
"abc" but no "b" and "bc"?
You would create an ngram filter that create grams from the first position
only. Take a look at EdgeNGramTokenFilter in contrib/analyzers.
