Term weighting and Term boost

Hello all, I am new to the Lucene scene and have a few questions regarding the term boost physolophy: Is the term boost equal to a term weight? Example: If I boost a term with 0.2 does this mean the term has a weight of 0.2 then? If this is not the case, how is the term weight of the query

RE: Indexing of deep structured XML

To really preserve the relationships in arbitrarily structured XML, you pretty much need to use a database that directly supports an XML query language like XQuery or XPath. Mick . -Original Message- From: [EMAIL PROTECTED]

Re: BooleanQuery question

No, you don't need required or prohibited, but you can't have both. Here is a rundown: * A required clause will allow a document to be selected if and only if it contains that clause and will exclude any documents that don't. * A prohibited clause will exclude any documents that contain that

RE: Ordening documents

William, The order of the results are going to be based on how well they match the query (i.e. weighted by relevancy). So although all of those values contain the term Palm, I would assume you would get the shorter entries (i.e. 1 3) before the longer ones (2) as they have a higher

RE: Ordening documents

Results are returned by order of score (highest first), not by the order they are inserted in the index. You may find the faq useful, http://lucene.sourceforge.net/cgi-bin/faq/faqmanager.cgi in particular take a look at the 'searching section'. hth, -John -Original Message- From:
