I m new to Lucene,
Just wondering if there is a way to realize sql 'Like' function in
Lucene as
following:
Select * from user_table where username like '%abc%'
I have checked with wildCardQuery, but it can not start with a '%'.
What about RegexQuery? How to use it?
WildcardQuery does support leading wildcard characters, but
QueryParser is what prohibits it. A custom QueryParser could be
created that removes this restriction. However, the potential of a
"too many clauses" exception is great with WildcardQuery so you'll
want to be careful. Check the list archives for this topic in gory
and never ending detail :)
