Subject more sql-like commands for solr
Date Tue, 07 Feb 2012 09:24:12 GMT
hi all,
    we have used solr to provide searching service in many products. I
found for each product, we have to do some configurations and query
expressions.
    our users are not used to this. they are familiar with sql and they may
describe like this: I want a query that can search books whose title
contains java, and I will group these books by publishing year and order by
matching score and freshness, the weight of score is 2 and the weight of
freshness is 1.
    maybe they will be happy if they can use sql like statements to convey
their needs.
    select * from books where title contains java group by pub_year order
by score^2, freshness^1
    also they may like they can insert or delete documents by delete from
books where title contains java and pub_year between 2011 and 2012.
    we can define some language similar to sql and translate the to solr
query string such as .../select/?q=+title:java^2 +pub_year:2011....
    this may be equivalent to apache hive for hadoop.
