46 | Revision 1.3 2004/11/29 03:15:13 kjdon
|
---|
47 | added some changes made by Emanuel Dejanu (Simple Words)
|
---|
48 |
|
---|
49 | Revision 1.2 2004/04/25 23:01:18 kjdon
|
---|
50 | added a new -M option to mg_passes, allowing maxnumeric to be altered - made this change to keep gsdl3 mg inline with gsdl2 mg.
|
---|
51 |
|
---|
52 | Revision 1.1 2003/02/20 21:18:24 mdewsnip
|
---|
53 | Addition of MG package for search and retrieval
|
---|
54 |
|
---|
55 | Revision 1.3 2001/09/21 12:46:42 kjm18
|
---|
56 | updated mg to be in line with mg_1.3f. Now uses long long for some variables
|
---|
57 | to enable indexing of very large collections.
|
---|
58 |
|
---|
59 | Revision 1.2 2001/06/12 23:23:42 jrm21
|
---|
60 | fixed a bug where mg_passes segfaults when trying to print the usage message.
|
---|
61 |
|
---|
62 | Revision 1.1 1999/08/10 21:18:12 sjboddie
|
---|
63 | renamed mg-1.3d directory mg
|
---|
64 |
|
---|
65 | Revision 1.3 1998/12/17 09:12:53 rjmcnab
|
---|
66 |
|
---|
67 | Altered mg to process utf-8 encoded Unicode. The main changes
|
---|
68 | are in the parsing of the input, the casefolding, and the stemming.
|
---|
69 |
|
---|
70 | Revision 1.2 1998/11/25 07:55:47 rjmcnab
|
---|
71 |
|
---|
72 | Modified mg to that you can specify the stemmer you want
|
---|
73 | to use via a command line option. You specify it to
|
---|
74 | mg_passes during the build process. The number of the
|
---|
75 | stemmer that you used is stored within the inverted
|
---|
76 | dictionary header and the stemmed dictionary header so
|
---|
77 | the correct stemmer is used in later stages of building
|
---|
78 | and querying.
|
---|
79 |
|
---|
80 | Revision 1.1 1998/11/17 09:35:13 rjmcnab
|
---|
81 | *** empty log message ***
|
---|
82 |
|
---|
83 | * Revision 1.3 1994/10/20 03:56:57 tes
|
---|
84 | * I have rewritten the boolean query optimiser and abstracted out the
|
---|
85 | * components of the boolean query.
|
---|
86 | *
|
---|
87 | * Revision 1.2 1994/09/20 04:41:52 tes
|
---|
88 | * For version 1.1
