: I thought that I have to use NGramFilter for wildcard search.
: But It was the wrong idea.
: Thanks, iorixxx

your confusion may be because using EdgeNGramFilter is a way to make 
"prefix" queries faster by precomputing hte prefixes as index time 
instead of at query time.  (trading disk space for speed)

having "q=enter" create a term query that can match "enter", 
"entertainment" and "enterprice" is the point in thta case -- but if 
executing a prefix query ("q=enter*") is fast enough for you, then 
you don't need EdgeNGramFilter.
