Hi! [I'm sorry for also posting this on the dev mailing list, but I was not sure in which one it would be best, so if there is a moderator, please kill either one.]
I'm planning on contributing to Lucene by adding a new kind of query. I dont know how to call it yet, but it would be a mix of BooleanQuery and ExactPhraseQuery. I would like to have a Query that is a BooleanQuery, but with a slight touch where it would boost results if it finds the query terms in a an exact phrase. For example, if I have terms A, B and C and I do a simple boolean search : A B C, I would like to have a query that behaves a bit like if I rewrote this query as such : +A +B +C "A B" "B C" "A B C" This would boost results where the exact string "A B C" or any substring like "A B" or "B C" are found. Of course I could rewrite all the queries, but it takes way too long to search which this algorithm. I wanted to know if anyone has any ideas in what direction I should go, or if its easy or not to implement this idea by modifying or extending some already existing Query classes. I'm fairly new to Lucene although I know a bit about search engines, idf, etc... but I've tried to understand BooleanQuery and ExactPhraseQuery to see how I could modify them and I'm having a bit of a problem understanding it all on my own I guess. Any help or comments would be appreciated, and if it works well I do think it would be a good addition to the Lucene code base (I think this query should be used as a default in the QueryParser if it works ok instead of a simple BooleanQuery). Thanks in advance for your help, Daniel Shane
