: Is it possible to add some kind of SortComparatorSource class / not : interface in new lucene releases with default behaviour to cache : ScoreDocComparators?
Anything's possible with a well written patch :) : > On a related note: have you considered using FunctionQueries (in teh Solr : > code base) to do your distance calculations? ... it's been discussed on : To say the truth i can't figure out how to switch from lucene sorting : capabilities to FunctionQueries. I have altered RequestHandler with : parsing SolrQueryRequest, building complex Query, ChainedFilters, : Sort objects and i do not want to change all that stuff. If you are currently doing a search and sorting on a custom Sort, then the scoring of your queries isn't currently being used at all -- so using a FunctionQuery is pretty easy: 1) impliment a ValueSource that does what you want (mainly: takes in a center point, and computes the distance for each doc from that point -- probably using two FieldCacheSource instances) 2) construct a FunctionQuery from your ValueSource, and use is as the main "meat" of your search -- all of your existing search criteria (your query and your filters) can be use as Filters if you want (since their scoring doesn't matter) or you can put them into a big BooleanQuery with a low boost on each (ie: 0.001), and a high boost on your FunctionQuery (ie: 10000). If you do care about the "relevency" scoring of your current queries, then picking exactly how the FunctionQuery fits into your existing Query structure and what the boost values should be gets trickier -- but it depends on how significant you want the numeric value of the function to be on the out come. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
