27 | .SH DESCRIPTION
|
---|
28 | .B mgbuild_4
|
---|
29 | is a
|
---|
30 | .B csh
|
---|
31 | script that executes all the appropriate programs in the correct order
|
---|
32 | to completely build an
|
---|
33 | .BR mg (1)
|
---|
34 | system database ready for queries to be made
|
---|
35 | by
|
---|
36 | .BR mgquery.
|
---|
37 | This program makes use of the
|
---|
38 | .BR mg_get (1)
|
---|
39 | script to obtain the text of the collection.
|
---|
40 | In
|
---|
41 | .BR mgbuild (1)
|
---|
42 | the build is done by two passes over the input text. The first
|
---|
43 | pass creates the compressed text dictionary and inverted file dictionary,
|
---|
44 | the second pass creates the compressed text and inverted file. What
|
---|
45 | .BR mgbuild_4
|
---|
46 | does is use a separate pass for each function. This will be slower but will
|
---|
47 | not require as much RAM at one time. Therefore, if your build is failing
|
---|
48 | due to running short of memory, then
|
---|
49 | .BR mgbuild_4
|
---|
50 | is worth a try.
