| 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.
