Subject Re: Solr Score threshold 'reasonably', independent of results returned
Date Tue, 28 Aug 2012 19:04:13 GMT

: Not really. The percentage given in other search packages is fairly
: bogus. You have to do a global batch analysis of all of the index to
: get a true scale for relevance.


*you* -- as the person in control of your solr instance, who kows 
everything about every document in the index, and has total control over 
the set of valid queries being executed against the index -- you *MAY* be 
able to compute a meaningful "threshold" of scores, based on the 
constraints you know/enforce.  But Solr can't do this, because in 
general Solr doesn't know those constraints (or if those constraints even 
exist) for an arbitrary index.
