yaz_hits ( resource id [, array searchresult] )
yaz_hits() returns the number of hits for the last
search.
Return Values
Returns the number of hits for the last search or 0 if no search was
performed.
The search result array (if supplied) holds information that
is returned by a Z39.50 server in the SearchResult-1
format part of a search response.

about hit counts for various parts of the query (subquery).

search terms in a query. Information for first
subquery is in $array[0], second subquery in $array[1], and so forth.
