Type of object to go into NamedList as part of SearchComponent#process(ResponseBuilder rb)
I am developing this system in which I adding custom SearchComponents
(last-components) after all the post-processing of the query.
server:
---
MyComponent extends SearchComponent :
@Override
public void process(ResponseBuilder rb) {
MySerializableType obj = new MySerializableType();
//populate obj after processing
rb.rsp.add("myresult" , obj );
}
}
client:
QueryResponse rsp = commonsHttpSolrServer.query( mySolrQuery);
MySerializableType obj = rsp.getResponse().get("myresult");
I was curious if the above mentioned code would work for any kind of
serializable type , T, as long as it implements Serializable . Would
there be any restrictions on the same (like only List of Strings -
List of Integers etc).
Thanks.
Query Boosting using both BQ and BF
Hi, I have a couple of questions related to query boosting using the dismax request handler. I'm using a recent 1.4 build (to take advantage of omitTf), and have also tried all of this with 1.3. To apply a query-time boost to the previous 3 months of documents in my index I use: published_date_d:[NOW-3MONTHS/DAY TO NOW/DAY+1DAY]^10.2 And, to provide a boosting that helps rank recently documents higher I use: recip(rord(published_date_d),20,5000,5)^5.5 This seems to be working well. But I have more boosting requirements. For example, I need to boost documents that are tagged as printed. So, I tried to add another bq parameter: is_printed_b:true^4.0 Also, tried to append this space-separated all in one bq parameter like this: published_date_d:[NOW-3MONTHS/DAY TO NOW/DAY+1DAY]^10.2 is_printed_b:true^4.0 Lastly, I need to apply a negative boost to documents of a certain type, so I use: -is_mp_parent_b:true^50.0 Not sure if it matters, but I have in schema.xml None of those variations return expected results (it's like the bq is being applied as a filter instead of just applying boosts). Q1. Can anyone confirm whether bf and bq can both be used together in solrconfig.xml? Q2. Is there a way I can do ths using only BF? How? Q2. Can I have multiple bq parameters? If so, do I space-separate them as a single bq, or provide multiple BQs? Q3. Am I formulating my BQs that use Boolean fields correctly?

No, the returned object is a NamedList data structure. It can contain the
basic java types (int/float etc.), strings, lists, maps and a couple of Solr
specific objects such as SolrDocumentList, SolrDocument

RE: Query Boosting using both BQ and BF
Some more experiments have helped me answer my own questions. > Q1. Can anyone confirm whether bf and bq can both > be used together in solrconfig.xml? yes > Q3. Can I have multiple bq parameters? If so, do I > space-separate them as a single bq, or provide > multiple BQs? Yes, multiple bq parameters work, space-separating multiple query terms in a single bq also works. Here's a snippet of my solrconfig.xml: published_date_d:[NOW-3MONTHS/DAY TO NOW/DAY+1DAY]^5.2 OR (published_date_d:[NOW-12MONTHS/DAY TO NOW/DAY+1DAY] AND report_type_id_i:1004)^10.0 OR (published_date_d:[NOW-6MONTHS/DAY TO NOW/DAY+1DAY] AND is_printed_b:true)^4.0 is_mp_parent_b:false^10.0 recip(rord(published_date_d),20,5000,5)^5.5 -Original Message- From: Dean Missikowski (Consultant), CLSA Sent: 08/03/2009 12:01 PM To: solr-user@lucene.apache.org Subject: Query Boosting using both BQ and BF Hi, I have a couple of questions related to query boosting using the dismax request handler.
