[447] | 14 | Revision 1.18 1999/08/10 22:46:33 sjboddie
|
---|
| 15 | changed format option result to QueryResults and added QueryLinks option
|
---|
| 16 |
|
---|
[421] | 17 | Revision 1.17 1999/07/30 02:24:42 sjboddie
|
---|
| 18 | added collectinfo argument to some functions
|
---|
| 19 |
|
---|
[403] | 20 | Revision 1.16 1999/07/19 00:16:58 sjboddie
|
---|
| 21 | no longer display documents that don't match all phrases in query string
|
---|
| 22 |
|
---|
[400] | 23 | Revision 1.15 1999/07/16 08:33:36 rjmcnab
|
---|
| 24 | Changed the logic for getting the results string slightly
|
---|
| 25 |
|
---|
[398] | 26 | Revision 1.14 1999/07/16 03:41:29 sjboddie
|
---|
| 27 | changed isApprox
|
---|
| 28 |
|
---|
[397] | 29 | Revision 1.13 1999/07/16 00:19:01 sjboddie
|
---|
| 30 | some changes to the way quoted queries are handled
|
---|
| 31 |
|
---|
[356] | 32 | Revision 1.12 1999/07/09 02:17:55 rjmcnab
|
---|
| 33 | Setting macros needed for a second query.
|
---|
| 34 |
|
---|
[349] | 35 | Revision 1.11 1999/07/07 06:13:10 rjmcnab
|
---|
| 36 | Added ability to combine two independant queries.
|
---|
| 37 |
|
---|
[347] | 38 | Revision 1.10 1999/07/07 05:49:35 sjboddie
|
---|
| 39 | had another crack at the format string code - created a new formattools
|
---|
| 40 | module. It can now handle {If} and {Or} statements although there's a
|
---|
| 41 | bug preventing nested if's and or's.
|
---|
| 42 |
|
---|
[337] | 43 | Revision 1.9 1999/07/01 22:48:46 sjboddie
|
---|
| 44 | had a go at getting a query result format string working
|
---|
| 45 |
|
---|
[298] | 46 | Revision 1.8 1999/06/27 22:02:11 sjboddie
|
---|
| 47 | author is added to queryresults if there is one
|
---|
| 48 |
|
---|
[295] | 49 | Revision 1.7 1999/06/26 01:10:18 rjmcnab
|
---|
| 50 | Made h, i, and n arguments saved in the compressed arguments.
|
---|
| 51 |
|
---|
[284] | 52 | Revision 1.6 1999/06/24 05:12:25 sjboddie
|
---|
| 53 | lots of small changes
|
---|
| 54 |
|
---|
[279] | 55 | Revision 1.5 1999/06/16 04:03:48 sjboddie
|
---|
| 56 | Now sets "cl" arg to "search" when going to a document from a search
|
---|
| 57 | results page. This allows the close book icon (in hierarchy toc) to
|
---|
| 58 | take you back to the results page if that's where you came from.
|
---|
| 59 | If you got to the document page somehow other than from a
|
---|
| 60 | classification or a search (i.e. if "cl" isn't set) then the close
|
---|
| 61 | book icon is disabled
|
---|
| 62 |
|
---|
[275] | 63 | Revision 1.4 1999/06/16 02:08:38 sjboddie
|
---|
| 64 | got queryaction working
|
---|
| 65 |
|
---|
[206] | 66 | Revision 1.3 1999/03/25 03:06:45 sjboddie
|
---|
| 67 |
|
---|
| 68 | altered receptionist slightly so it now passes *collectproto to
|
---|
| 69 | define_internal_macros and define_external_macros - need it
|
---|
| 70 | for browseaction
|
---|
| 71 |
|
---|
[183] | 72 | Revision 1.2 1999/03/03 20:26:50 rjmcnab
