> 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.
The SearchResult-1 format can be used to obtain information
about hit counts for various parts of the query (subquery).
In particular, it is possible to obtain hit counts for the individual
search terms in a query. Information for first
subquery is in $array[0], second subquery in $array[1], and so forth.
