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.
