I have a situation where I'm indexing database entries and have
fields such as:
name
sku
model
category name
description
features
specifications
I am trying to set a priority higher for the name, category name, and
description.
I've tried setting the fields' boost values as I've indexed the db
and it seemed to have little or no result.
When I tried to do the queries, I started using the
MultiFieldQueryParser but found that those don't have priority or
boost values you can set on any of the Fields at query time. Then I
tried to have separate query parsers - one for each field. That way
I could set a boost level for each of the queries created by those
query parsers. I joined them together with a BooleanQuery and all of
them set to BooleanQuery.Occur.SHOULD. I ended up setting the
features, specifications, and description to default to
Query.Operator.AND and that helped, but the boost value seems to do
nothing.
I try to set the categoryParser's query boost to 4.0f, then 8.0f,
then 20.0f and have tried downgrading other queries, but the results
don't change at all in their order.
I am using 1.9.1 and for my database I'm using hibernate to mysql 5
and ArrayLists with the bag mapping in hibernate.
Does anyone have any thoughts or suggestions?
Thanks!
Jeremy
