Subject Re: How to formulate query
Date Mon, 12 Oct 2015 19:14:07 GMT
Hello,
Even number of word can be used as scoring factor, but just for beginning.
You can cut the first word into separate field with _field mutating update
processor_ see
http://lucene.apache.org/solr/5_3_1/solr-core/org/apache/solr/update/processor/FieldMutatingUpdateProcessorFactory.html
then you can use query syntax to specify field:, boost^10 and wildcard*.
All such clauses might be combited with spaces as optional ones.
