Thanks for your reply. How can I support suffix search?
Name: Hello_world Search: *world And I'll get hello_world as a result.

The WordDelimeterFilter will split on the underscore, which means that the term "hello" is in the index for that document. Leave that filter out if you really do want an exact match. Searching for "*" by itself is not how you match all documents. It may work, but it is a wildcard search, which means under the covers that it's a search for every term in the index for that field. It's SLOW. The special shortcut *:* (this must be the entire query with no field name, and I'm assuming the standard query parser here) is what you want for all documents. In terms of user input, this is what you want to use when the user leaves the search box empty. If you're using dismax or edismax, then you would send an empty q parameter or leave it off entirely, and define a default q.alt parameter in solrconfig.xml, set to *:* for all docs.
