> ps = ? - something that affects boosting, but how?
Lets say your query is apache solr. (without quotation marks)
Lets say these three documents contains all of these words and returned.
1-) solr is built on the top of apache lucene.
2-) apache solr is fast, mature and popular.
3-) solr is hosted under apache umbrella.
Even if you don't use pf and ps parameters, those documents will be in result
set anyway. Lets say that they appear in this order 1,2,3.
Then we include pf and ps parameter, q=apache solr&pf=title^1.2&ps=1
Second document is boosted, lets say it comes first now. The order is changed.
The documents - that have the all query words close each other - are boosted.
Again the same three documents are returned.
