field based boosting
Hello All, I am having a trouble in following an approach for field boosting. I have possibility of two cases in searching. One is similar to DisMax, which uses field boosting, and the second one is normal. To go for which of them is based on user query ( probably inside query parser). So I can not use DisMax as default, but I need to provide field based boosting. To be brief, looking at query string, 1) if there are no fields supplied as part of the query, I need to search for the input-query terms in a set of default field list including support for field boosting. 2) If the user has supplied some field name as part of the query then I do some other modifications to the query like query expansion, etc. As , whether the field name is provided are not is to be judged in query parser ( as far as I know ), which might be the right way of providing both of above features. Thanks.
