Hi Daniel, >> so a doc from 1973 should get a boost of 1.1973 and a doc of 1975 should >> get a boost of 1.1975 . > > The boost is stored with a limited resolution. Try boosting one doc by 10, > the other one by 20 or something like that.
You're right. I thought that with the float values the resolution should be good enough! But there is only a difference in the score with a boosting diff of 0.2 (e.g. 1.7 and 1.9). I know that there were many questions on the list regarding scoring better new documents. But I want to avoid any overhead like "FunctionQuery" at query time, and in my case I have some documents which have same values in many fields (=>same score) and the only difference is the year. However I don't want to overboost the score so that the scoring for other criteria is not considered. Shortly spoken: As a result of a search I have a list of book titles and I want a sort by score AND by year of publication. But for performance reasons I want to avoid this sorting at query-time by boosting at index time. Is that possible? thanks, Martin > -- Universitaetsbibliothek Heidelberg Tel: +49 6221 54-2580 Ploeck 107-109, D-69117 Heidelberg Fax: +49 6221 54-2623 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
