: Hi, i added some code to *DirectUpdateHandler2.java's doDeletions()* (solr
: 1.2.0) ,and got the solution i wanted.(logging duplicate post entry-i.e old
: field and new field of duplicate post)
:
:
: Document d1=searcher.doc(prev); //existing doc to be deleted
: Document d2=searcher.doc(tdocs.doc()); //new doc
: String oldname=d1.get("name");
: String id1=d1.get("id");
: String newname=d2.get("name");
: String id2=d1.get("id");
: out3.write(id1+","+oldname+","+newname+"\n");
:
: But i dont know ,wether the performance of solr will be affected by this.
: Any comment on the performance issue for the above solution is welcome...
it's probably going to be painfully slow -- you're probably going to be a
lot better off avoiding the use of searcher.doc and instead stick with
using the FieldCache, but there are trade offs there as well, it's largely
going to depend on how often you're doing adds vs. commits.
BTW: as i mentioned before, it probably make more sense to implement this
in an UpdateProcessor instead of hacking DirectUpdateHandler2 ... that way
you'll be able to upgrade Solr without worryiing about losing/redocing
your changes.
