COUNT_HITS

Returns the number of hits for the specified query. You can call COUNT_HITS in exact or estimate mode. Exact mode returns the exact number of hits for the query. Estimate mode returns an upper-bound estimate but runs faster than exact mode.

Syntax

CTX_QUERY.COUNT_HITS ( 
    index_name  IN VARCHAR2, 
    text_query  IN VARCHAR2, 
    exact       IN BOOLEAN  DEFAULT TRUE,
    part_name   IN VARCHAR2 DEFAULT NULL
) RETURN NUMBER; 

index_name

Specify the index name.

text_query

Specify the query.

exact

Specify TRUE for an exact count. Specify FALSE for an upper-bound estimate. Specifying FALSE returns a less accurate number but runs faster.

part_name

Specify the name of the index partition to query.

Notes

If the query contains structured criteria, you should use SELECT COUNT(*).
