== Citation search in SOLR and second-order operators ==
* Roman Chyla, Astrophysics Data System, roman.chyla AT (cfa.harvad.edu|gmail.com)
Citation search is basically about connections (Is the paper read by a friend of mine more important than others? Get me a paper read by somebody who cites many papers/is cited by many papers?), but the implementation of the citation search is surprisingly useful in many other areas.
I will show 'guts' of the new citation search for astrophysics, it is generic and can be applied recursively to any Lucene query. Some people would call it a second-order operation because it works with the results of the previous (search) function. The talk will see technical details of the special query class, its collectors, how to add a new search operator and how to influence relevance scores. Then you can type with me: friends_of(friends_of(cited_for(keyword:"black holes") AND keyword:"red dwarf"))
