: Exactly in this scenario, I would love to use my custom generated document : id. : The array reference number is MyId & its value is some-interested-value : matched to MyID. : : So,how can I generate custom document id.?
you can't .. you can index you custom "MyID" value and use the FieldCache to look it up -- using the lucene docid. That's what Karl is refering to: he uses the lucene docid as the *index* in the array, and his MyId values are *stored* in the array. : > -----Original Message----- : > From: Chris Hostetter [mailto:[EMAIL PROTECTED] : > Sent: Friday, December 15, 2006 6:35 AM : > To: java-user@lucene.apache.org : > Subject: Re: Lucene id generation : > : > : > Karl: it sounds like you are just refering to using the : > lucene docid as an array index for the FieldCache of your : > "MyID" field ... that's a perfectly valid use of the docid, : > the key being that you aren't expecting the id to contain any : > meaningful data itself -- it's just a refrence number. : > : > : > if you are trying to think of Lucene's docid as a meaningful : > : > number, you : > : > are doing something wrong. : > : : > : There is this one place where I use it.
