: duplicated them to give the words they contain more weight. So I will not : want to return higher PositionIncrement for each instance of a field, just : those which I'm interested in (title/headers). Can this be done somehow : without injecting a "magic string", as Chris called it?
there are multiple levels to the API for indexing that you can use ... you at the String/Reader+Analyzer level of the API, you could use a magic token in your Strings to tell your Analyzer when to set a high increment, or you can stich together multiple strings into a single "Field" and use the increment gap to get a high increment only after each one; or you can skip the String/Reader+Analyzer aspect completley and just add a TokenStream of your own ceation directly to a Field instance. The point is there are lots of ways to get an arbitrary increment at an arbitrary point in your stream. Some may seem kludgier then others, but the "right" way is subjective depending on what kind of data strucutres you already have to work with. : getPositionIncrementGap is a member function of StandardAnalyzer, not : StandardTokenizer. Since my use case is a bit different than what you It's a method of the Analyzer API. whatever Analyzer you tell IndexWriter to use needs to implement that method, if you are writing your own Analyzer that uses StandardTokenizer you can implement it however you want. : You have pretty much understood my use case for position increment 0 - but I : thought this is possible to do with customizing a Scorer? I haven't gotten Who said anything about a custom Scorer? : that deep into Lucene myself (yet)... : I'm not entirely sure I understand the consequences of storing more than one : Term in the same position. What I understood from your explanation is that Position values only affect proximity. There is nothing special about two terms at the same postion -- they only matter as relative distances from each other and other Terms when you do a PhraseQuery or a SpanNearQuery (etc...). If the positions of A and B differ by 10, then they match with slop of 15 and not a slop of 5. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
