Often documents can be divided in "metadata" and "contents" sections. Say you're indexing Web pages, you could index them with HEAD data all in one field, and the BODY content in another. While also creating separate fields for every HEAD field, e.g. TITLE etc.
At search time, you rewrite every query to become "+head:(query) +body:(query)" using MultiFieldQueryParser. This way you don't have to create an "all" field that contains everything, head + body. I will increase your index size, no doubt. Might increase indexing time too. --Renaud -----Original Message----- From: Mohammad Norouzi [mailto:[EMAIL PROTECTED] Sent: Sunday, July 15, 2007 9:40 PM To: java-user@lucene.apache.org Subject: Re: search through all fields On 7/14/07, Grant Ingersoll <[EMAIL PROTECTED]> wrote: > > I think he means index all your different fields into a single field > named "all".
