- MAP21: VERONICA
- ---------------
-
- "One must learn by doing the thing; though you think
- you know it, you have no certainty until you try."
- -- Publilius Syrus, Moral Sayings
-
-
- Bouncing around Gopherspace, finding neat files and leaving bookmarks,
- is fun for a while. Soon, however, you are going to want to find a
- way to locate stuff in Gopherspace a little more quickly.
-
- That's where Veronica comes in. Veronica -- Very Easy, Rodent-Oriented,
- Net-Wide Index to Computerized Archives -- is a search tool that allows
- you to quickly scan Gopherspace for particular files and directories.
-
- Veronica is a program that you access through Gopher. Veronica asks
- you to enter a keyword, and it then searches through a database
- of over 5,500 Gopher servers and over 10 million Gopher "items"
- for files and directories whose titles contain your keyword.
-
- What makes Veronica REALLY amazing is that it not only finds these
- files and directories, it also *GETS* all of these files and directories
- and places them on a temporary Gopher menu that you can browse through!
- This temporary menu works just like any other Gopher menu!
-
- Let's take a look at a basic Veronica search. I access my site's
- Gopher client by typing "gopher" on the command line, and the following
- menu appears on my screen:
-
-
- Rice CMS Gopher 2.4.0 GOPHER.SQUIRREL.COM
- 1/8
- (root menu)
- <document> Information about the Squirrel Gopher Server
- <document> What's new in the Squirrel Gopher
- <menu> Network Resources, Services and Information
- <phonebk> Squirrel staff directory
- <menu> Squirrel Human Resources Information
- <menu> Potpourri, Miscellaneous Topics
- <menu> Local Squirrel Archives
- <menu> Other Gopher Servers
- <menu>_ Search all of Gopherspace using Veronica - 4800+ servers
-
-
- Since I used the UNIX Gopher client the first two days of this week, I
- figured it was only fair to use the VM Gopher client for two days as
- well :)
-
- I move the cursor down to the "Search Gopherspace using Veronica"
- menu line, press enter, and the following menu appears on my screen:
-
-
- Rice CMS Gopher 2.4.0 gopher.tc.umn.edu
- 1/10
- Search all of Gopherspace using Veronica - 4800+ servers
- <menu> About Veronica: Documents, Software, Index-Control Protocol
- <menu> Experimental Veronica Query Interface: Chooses Server for You!
- <search> Find ONLY DIRECTORIES by Title word(s) (via SUNET)
- <search> Find ONLY DIRECTORIES by Title word(s) (via U of Manitoba)
- <search>_ Find ONLY DIRECTORIES by Title word(s) (via U T Dallas)
- <document> Frequently-Asked Questions (FAQ) about veronica - July 29,1994
- <document> How to Compose Veronica Queries - June 23, 1994
- <search> Search Gopherspace by Title word(s) (via SUNET)
- <search> Search Gopherspace by Title word(s) (via U of Manitoba)
- <search> Search Gopherspace by Title word(s) (via U T Dallas)
-
-
- Notice that not only do I get to choose which Veronica program site
- I want to conduct my search through, I also get to choose between
- two types of searches:
-
- 1. "Search Gopherspace by Title word(s)" which will show me EVERY FLE
- AND DIRECTORY in Gopherspace whose title contains my keyword, or
-
- 2. "Find ONLY DIRECTORIES by Title word(s)" which will show me ONLY
- THE DIRECTORIES (a.k.a. menus) in Gopherspace whose titles contain
- my keyword.
-
- Obviously, the return from an "ONLY DIRECTORIES" search will be much smaller
- than that from a "Search Gopherspace" search. If you are using a common
- word as your keyword (such as "Internet", "Gopher", "Economics", etc.),
- your best bet is to do an "ONLY DIRECTORIES" search to keep from being
- flooded with returns :)
-
- I want to do a search of every Gopher directory on the planet that
- has the word "Roadmap" in it.
-
- The choice of which site I conduct my search through is completely up
- to me. There should not be a difference between the sites and the results
- that I will get (notice I said *should* not), so I can pick any site that
- I want. Since my former best friend used to live in Dallas, I move the
- cursor down to the "Find ONLY DIRECTORIES by Title word(s) (via U T
- Dallas)" search entry, press enter, and the following appears on my
- screen:
-
- Enter keyword(s):
-
- The keyword I want Veronica to look for is "Roadmap," so I type
-
- Roadmap
-
- press enter, prop my feet up on the desk, and wait for something to
- appear on my screen.
-
- Eventually, the following menu appears on my screen:
-
-
- Rice CMS Gopher 2.4.0 veronica.utdallas.edu
- 1/8
- Find ONLY DIRECTORIES by Title Word(s)
- <menu> Roadmap & Guide to Finding Information
- <menu> Roadmap to Institutional Data
- <menu>_ ROADMAP
- <menu> Roadmap to Risk (Graphics Files -- pict format)
- <menu> Roadmap to Risk (ASCII)
- <menu> Roadmap to Human Resources
-
-
- COOL! Although each of these menus are located on different servers
- around the world, I can access them ALL from this menu (although
- further investigation shows that NONE of these menus have anything
- to do with this workshop <<pout>>).
-
- Isn't Veronica NEAT?? There are a few more Veronica commands that you
- can use, but I'll let you discover them in tonight's homework :)
-
-
- ACCESSING VERONICA
-
- If you wander around Gopherspace enough, you are bound to find a
- site with a link to Veronica. Chances are, your site even has
- its own Veronica link!
-
- I would strongly recommend finding a Veronica menu somewhere and
- planting a bookmark there. You will find that Veronica is an
- ESSENTIAL Internet tool, and not having Veronica in your booklist
- is going to be a BIG mistake.
-
- You can find Veronica menus on most of the Gopher sites that you
- can telnet to (see the list of telnet Gopher sites in MAP19),
- and you can also access the Veronica menu through the University of
- Minnesota's Gopher server (gopher.micro.umn.edu 70).
-
-
- PERSONAL OBSERVATIONS
-
- I have personally had some problems with Veronica. I'm not sure if
- I am the only one who has had these problems, or if these problems
- are universal -- it is quite possible that I am living in a Veronica
- "black hole" and Veronica works perfectly well everywhere else but
- Alabama.
-
- It is my personal experience that Veronica is so over-burdened that
- your chances of getting the Veronica program to accept your keyword
- on the first (or even the fifth) try are pretty slim. More likely
- than not, you are going to get a
-
- *** Too many connections - Try again soon. ***
-
- message. This can become very frustrating very quickly.
-
- Other times, you will encounter the now-famous
-
- Empty menu; no items selected or nothing available
-
- error message that we discussed the other day. This is also frustrating,
- especially when you have to retype your keyword every time this error
- appears on your screen.
-
- The final error that I seem to encounter a lot in Veronica is the one
- that tells me that Veronica has found nothing matching my keyword.
- Unfortunately, experience has shown me that this may or may not be accurate.
-
- There are a couple of things that you have to remember when using
- Veronica:
-
- - Veronica is *incredibly* overloaded
- - If a Veronica keyword search does not work the first
- time, keep trying
- - When Veronica works, it is a thing of beauty
- - When Veronica doesn't work, it gives you error messages
- that may or may not be accurate
- - If you get an error message, try your keyword again
- - The most important ingredient in any Veronica search
- is *PATIENCE*
-
- While I was writing this lesson, I was also attempting a Veronica
- search using the keyword "Crispen". After 32 attempts, I still have
- not been able to get Veronica to accept this keyword without giving
- me an error message :(
-
-
- HOMEWORK:
-
- 1. Play around with Veronica :)
-
- 2. Find the "Frequently Asked Questions (FAQ) about Veronica"
- and the "How to Compose Veronica Queries" documents and
- read them. These documents can be found in most Veronica
- menus. You can also find them in the "Search all of
- Gopherspace Using Veronica" menu on the University of
- Minnesota's Gopher server.
