Hi Solr team.
I’ve got a question about scoring; when we make a search like this: “bush
obama^9”, we always have a 0.0 score.
Should we not have a higher score we the document contains both “bush” and
“obama”?
Our default search filed is defined like this:
<field name="nFullText" type="text" indexed="true" stored="true"
termVectors="true"/>
Here is debug result:
<lst name="debug">
<str name="rawquerystring">bush obama^9</str>
<str name="querystring">bush obama^9</str>
<str name="parsedquery">nFullText:bush nFullText:obama^9.0</str>
<str name="parsedquery_toString">nFullText:bush
nFullText:obama^9.0</str>
<lst name="explain">
<str name="news_584440">
