|
---|
15 | small change to do with new collection-level metadata
|
---|
16 |
|
---|
17 | Revision 1.18 1999/08/10 22:46:33 sjboddie
|
---|
18 | changed format option result to QueryResults and added QueryLinks option
|
---|
19 |
|
---|
20 | Revision 1.17 1999/07/30 02:24:42 sjboddie
|
---|
21 | added collectinfo argument to some functions
|
---|
22 |
|
---|
23 | Revision 1.16 1999/07/19 00:16:58 sjboddie
|
---|
24 | no longer display documents that don't match all phrases in query string
|
---|
25 |
|
---|
26 | Revision 1.15 1999/07/16 08:33:36 rjmcnab
|
---|
27 | Changed the logic for getting the results string slightly
|
---|
28 |
|
---|
29 | Revision 1.14 1999/07/16 03:41:29 sjboddie
|
---|
30 | changed isApprox
|
---|
31 |
|
---|
32 | Revision 1.13 1999/07/16 00:19:01 sjboddie
|
---|
33 | some changes to the way quoted queries are handled
|
---|
34 |
|
---|
35 | Revision 1.12 1999/07/09 02:17:55 rjmcnab
|
---|
36 | Setting macros needed for a second query.
|
---|
37 |
|
---|
38 | Revision 1.11 1999/07/07 06:13:10 rjmcnab
|
---|
39 | Added ability to combine two independant queries.
|
---|
40 |
|
---|
41 | Revision 1.10 1999/07/07 05:49:35 sjboddie
|
---|
42 | had another crack at the format string code - created a new formattools
|
---|
43 | module. It can now handle {If} and {Or} statements although there's a
|
---|
44 | bug preventing nested if's and or's.
|
---|
45 |
|
---|
46 | Revision 1.9 1999/07/01 22:48:46 sjboddie
|
---|
47 | had a go at getting a query result format string working
|
---|
48 |
|
---|
49 | Revision 1.8 1999/06/27 22:02:11 sjboddie
|
---|
50 | author is added to queryresults if there is one
|
---|
51 |
|
---|
52 | Revision 1.7 1999/06/26 01:10:18 rjmcnab
|
---|
53 | Made h, i, and n arguments saved in the compressed arguments.
|
---|
54 |
|
---|
55 | Revision 1.6 1999/06/24 05:12:25 sjboddie
|
---|
56 | lots of small changes
|
---|
57 |
|
---|
58 | Revision 1.5 1999/06/16 04:03:48 sjboddie
|
---|
59 | Now sets "cl" arg to "search" when going to a document from a search
|
---|
60 | results page. This allows the close book icon (in hierarchy toc) to
|
---|
61 | take you back to the results page if that's where you came from.
|
---|
62 | If you got to the document page somehow other than from a
|
---|
63 | classification or a search (i.e. if "cl" isn't set) then the close
|
---|
64 | book icon is disabled
|
---|
65 |
|
---|
66 | Revision 1.4 1999/06/16 02:08:38 sjboddie
|
---|
67 | got queryaction working
|
---|
68 |
|
---|
69 | Revision 1.3 1999/03/25 03:06:45 sjboddie
|
---|
70 |
|
---|
71 | altered receptionist slightly so it now passes *collectproto to
|
---|
72 | define_internal_macros and define_external_macros - need it
|
---|
73 | for browseaction
|
---|
74 |
|
---|
75 | Revision 1.2 1999/03/03 20:26:50 rjmcnab
|
---|
76 |
|
---|
77 | Modified stuff.
|
---|
