Let us now understand ord() or rord() using a scenario. Assuming there are four documents that have been indexed with the holding values 60, 60, 85, and 90, respectively, for a field, say field x. In this situation, ord(x) is going to return values ranging from 1 to 3, even though we have four documents in the index. The reason behind this is that out of four documents, only three of them are distinct (fields where the value 60 has been repeated). There is another difference but a tricky one, that is, the original values are not in a linear pattern.
Thus, in totality, we have three clauses that Solr would love to play around with. Assume that there is another document where this phrase doesn't match, but it has both the terms available individually and scattered out in there. In this case, only two of the clauses would match. As par Lucene's scoring algorithm, the coordination factor for the first document (which matched the complete phrase) would be higher, assuming that all the other factors remain the same. Configuring autophrase boosting Let me inform you, autophrase boosting is not enabled by default.
