| Background: although the contract of the Scorer class requires that | |
| documents be iterated in order of doc id, this was not true in early | |
| versions of Lucene. Many pieces of functionality in the current Lucene code | |
| base have undefined behavior if this contract is not upheld, but in some | |
| specific simple cases may be faster. (For example: disjunction queries with | |
| less than 32 prohibited clauses; This setting has no effect for other | |
| queries.) | |
| <p /><p /> | |
| Specifics: By setting this option to true, docid N might be scored for a | |
| single segment before docid N-1. Across multiple segments, docs may be | |
| scored out of order regardless of this setting - it only applies to scoring | |
| a single segment. | |
| Being static, this setting is system wide. | |
