Hello. I have an SQL database with documents having an ID, TITLE and SUMMARY. I am using the DIH to index the data.
In the DIH dataConfig, for every document, I would like to do something like: <field column="TITLE" name="title"* boost="2.0"* /> In other words, "A match on any document's title is worth twice as much as a match on other fields" In my schema, I have omitNorms set to false. 1) How can I do this in the DIH? 2) Apart from omitNorms making the index bigger, I thought that index-time boost would give us more performance than doing the very same boosting at query time over and over again. Is that correct? 3) I also came across the Lucene FAQ at http://wiki.apache.org/lucene-java/LuceneFAQ#What_is_the_difference_between_field_.28or_document.29_boosting_and_query_boosting.3F where the following interesting statement seems to contradict what I'm trying to achieve: *Index time field boosts are worthless if you set them on every document. * Any hint would be much appreciated. Thanks. Arcadius.
