A set of tuple counts: arises when a cs_xref_query is executed with cs_xref_query_execute().
The total number of results for a query is estimated as (matched/scanned)*(scanned+unscanned).
The .scanned and .unscanned fields are only populated if the cs_xref_query is specified with the csxrqf_populate_counters (or csxrqf_all) flag. The .matched field is always populated.
Defined in file cs_types.h.
| cs_size_t | scanned | The total number of tuples examined during query execution: the tuples enumerated by matched, plus all tuples examined but discarded as non-matching. |
| cs_size_t | unscanned | The number of tuples that were indexed for examination but ultimately not examined (generally because the specified limit was reached). |
| cs_size_t | matched | The number of tuples in the query result set. |
