VI.d Setting Up Searches ------------------------ Index searches (Type=7) are among the more powerful features a Gopher server can offer. Several different search engines are available for Gopher servers to use. NeXT-based servers can offer search engines based on NeXT's digital library; WAIS-based searches are available as well. The OpenVMS Gopher Server offers three kinds of searches: traditional GREP searching, Shell searching, and Command searching. The results of a successful search are generally formatted in a menu to the client, each menu item representing a hit on the search terms. The general format of a search specification requires Type=7 and Path=7, where is specific to the kind of search engine to be used. Presentation of hits returned by the search engine is usually in sorted order. The SortXXX: options in the configuration file specify the sort default for each search engine (GREP, CMD1, Shell) and are normally TRUE. The configuration defaults for any of these engines may be overriden in the search specification by a ":sort:" or ":nosort:" token *immediately following the "7" in the Path= specification, as in: Path=7:sort: or Path=7:nosort: .
