- What is gindexd?
- ----------------
-
- Gindexd allows you to serve indexes of data residing on a gopher
- server. Gindexd will allow you to search through a voluminous amount
- of data quickly. It is preferred that you use the built in indexing
- in the gopher server though, see the gopherd man page for more
- information.
-
- As of release 1.0, gindexd is now a symbolic link to gopherd.
-
-
- How To Set Up An Index Server
- -----------------------------
-
- An full-text index is used to rapidly find data in a set of files.
- The first step in making a gopher index server is to build the index
- on your data files.
-
- For the NeXT this command is called ixBuild.
- For the WAIS server this command is called waisindex.
-
- Okay, how about a real world example? Suppose that you have a
- directory structure that contains your grandmother's favorite recipes
- located in /home/mudhoney/recipes/. Also assume that there are
- subdirectories for cakes, pies, and stews i.e. :
-
- -------
- % pwd
- /home/mudhoney/recipes
-
- % ls
- cakes/ pies/ stews/
-
- -------
-
- Assume also that you will be running a gopher data server on the
- directory /home/mudhoney/recipes.
-
-
- Building the index with the NeXT and ixBuild.
- ---------------------------------------------
-
- Go into the directory you want as the root level of your index. If
- you want to index all of the recipes you'd type the following:
-
- cd /home/mudhoney/recipes
- mkdir .index
- ixBuild -V
-
- This will make an index in the file:
-
- /home/mudhoney/recipes/.index/index.ixif
-
- If you wanted to just index the pies subdirectory you would do the
- following:
-
- cd /home/mudhoney/recipes/pies
- mkdir ../.index
- ixBuild -V -i../.index/index.ixif
-
- ...or
-
- cd /home/mudhoney/recipes/pies
- mkdir .index
- ixBuild -V -i.index/index.ixif pies
-
- It's important that the filenames that are generated by ixBuild have
- the same format that is given by the gopher server! You can easily
- test this by using ixFind. Make sure it doesn't contain the entire
- path. Also make sure that when you're indexing a subdirectory that the
- previous directories up to the root directory get added to the path by
- ixBuild.
-
-
- Building the Index with waisindex
- ---------------------------------
-
- With waisindex it isn't necessary to be in the root directory of the
- gopher server. The WAIS indexer stores filenames with their absolute
- paths, this causes problems later.
-
- If you want to index the whole recipe collection in
- /home/mudhoney/recipes you'd do the following:
-
- waisindex -r /home/mudhoney/recipes
-
- The waisindex program will create a bunch of files starting with
- index. These files together comprise an index to your data.
-
-
- If you wanted to just index the pies subdirectory you would do the
- following:
-
- waisindex -r /home/mudhoney/recipes/pies
-
-
- Starting Up the Index Server
- ----------------------------
-
- Now that you have indexes you can actually run the gopher index server
- on them. The first step you should do is to move the index files into
- a directory all their own. Let's say that you chose
- /home/mudhoney/indexes/recipes.
-
- So, for the NeXT you would:
-
- mkdir /home/mudhoney/indexes/recipes
- mkdir /home/mudhoney/indexes/recipes/.index
- cp {originaldir}/.index/index.ixif /home/mudhoney/indexes/recipes/.index
-
- For the WAIS version you would:
-
- mkdir /home/mudhoney/indexes/recipes
- cp index.* /home/mudhoney/indexes/recipes
-
- The next step is very important. You must create a "hostdata" file in
- the same directory as the indexes. In this case you'd make a file
- called "/home/mudhoney/indexes/recipes/hostdata".
-
- In this file you need 2 to 3 pieces of information. The first line of
- the hostdata file should contain the hostname of the machine that is
- running a gopher server for the indexed data. The second line
- contains the port that the data server is running at.
-
- If you're running the WAIS version of gindexd then you'll have to add
- a third line. This line should contain the directory of the gopher
- data server. Gindexd will strip this off of all responses it sends
- back. (This is why the WAIS indexing engine causes problems, it puts
- in the whole path, not the relative path)
-
- For example, our recipes index "hostdata" file would look like the
- following:
-
- mudhoney.micro.umn.edu
- 150
- /home/mudhoney/recipes
-
- This assumes that there is a gopher data server running on
- mudhoney.micro.umn.edu at port 150. The nice part about using the
- hostdata file is that you can move indexes off to other machines. Put
- the indexes on the big sexy computers. And put the actual data off on
- some sluggish machine.
-
- {As of version 0.7 you can override the default title name returned by
- gindexd. Add the keyword "ShowHeadline" at the end of the hostdata
- file.
-
- Also you can add the keyword "ShowDate" in the hostdata file. This will
- put the date of the document in the Title.
- }
-
- After this step is completed you can actually run the gindexd daemon!
- There two required options. The usage is:
-
- gindexd [-DI] <indexdirectory>/[databasename] <portnumber>
-
- The -p sets the port to run at. You can use any unused port. The -i
- sets the index directory to look for indexes. (For the NeXT version
- do *not* specify the subdirectory ".index". Give the directory above
- it instead). The -D specifies that we should run in debug mode. The
- -d parameter is only useful for the Wais indexer, it allows you to
- specify a database name other than "index".
-
- The -I parameter should be used when you are starting the indexer from
- inetd. It's also useful when testing whether or not your indexes have
- been built successfully.
-
- The -H parameter can be used to specify an alternative hostdata file.
-
- Here is the command we would use to start our recipe index daemon:
-
- gindexd /home/mudhoney/indexes/recipes 151
-
-
-
- Setting Up Links To Index Servers
- ---------------------------------
-
- This part is pretty simple. Just create a .link file on your gopher
- data server that contains the pertinant information. Just make sure
- that you get the "Type=" line correct. An index server is itemtype 7.
-
- Here's what we would use for our recipe example:
-
- Type=7
- Host=mudhoney.micro.umn.edu
- Port=151
- Path=
- Name=Grandma's Recipe Book
-
-
- By fiddling with the Path= parameter and changing the type to "Type=1"
- you can do some interesting things. When the user accesses the
- following list they will get a directory of all the stuff that has
- rhubarb pies in it.
-
- Type=1
- Host=mudhoney.micro.umn.edu
- Port=151
- Path=rhubarb pie
- Name=Grandma's Rhubarb pie recipes.
-
- This type of thing is especially usefull for data that changes
- rapidly, like news. We've set up one such link that searches our
- campus newspaper for the "What's Doing" schedule of events.
