i tried openNLP but found it's not very good for search queries
because it uses grammar features like capitalization.
i coded up a bayesian model with mutual information to model dependence
between terms. ex. grouping "stanford university" together in the query
"stanford university solar"

Do you mind sharing that please?

Subject: Re: Query modification
Hi,
I actually did something similar on http://researchwatch.net/
if you search for "stanford university solar", it will process the query
by tagging the stanford university to the organization field.
I created a querycomponent class and altered the query string like
this(in scala but translatable to java easily):
override def prepare(rb: ResponseBuilder){
val params: SolrParams = rb.req.getParams
if(params.getBool(COMPONENT_NAME, false)){
val queryString = params.get("q").trim //rb.getQueryString()
val entityTransform = new ClearboxEntityDetection
val (transformedQuery, explainMap) =
entityTransform.transformQuery(queryString)
rb.setQueryString(transformedQuery)
rb.rsp.add("clearboxExplain", explainMap)
}
}

If I wanted to intercept a query and turn
q=romantic italian restaurant in seattle
into
q=romantic tag:restaurant city:seattle cuisine:italian
would I subclass QueryComponent, modify the query, and pass it to super?
Or
is there a standard way already to do this?
What about changing it to
q=romantic city:seattle cuisine:italian&fq=type:restaurant
would that be the same process, or is there a nuance to modifying a query
into a query+filterQuery?
