0. Created file on 2/May/94
1. Added patches to main.c to use sizeof(char*) instead of 4 in relevant
places. Same for other pointer mallocs.
-- bg 2 May 1994
2. Successfully ported to DEC-ALPHA: changes to routines in agrep/agrep.c
-- bg 10 May 1994
3. Added the new mgrep routine. Removed bugs (pattern too long) related to
using shift-or/and algorithm to search for booleans: now it uses mgrep.
-- bg 26-30 May 1994
4. Added delimiter processing even with -f and -m.
-- bg 31 May - 2 June 1994
5. Added structured queries support in June 1994
-- Syntax of glimpse:
glimpse <options> 'a1=v1,a2=v2...' (series of ORs)
glimpse <options> 'a1=v1;a2=v2...' (series of ANDs)
-- Syntax of glimpseindex:
glimpseindex -s <options/files>
-- NOTES:
v1, v2 etc. must lie within the range of a1, a2, etc., i.e., if
a1 is in the region [offset, offset+len] in a file, v1 must lie
compleletely within that range.
A new glimpse-file called .glimpse_attributes is created to hold
the attributes discovered while indexing with -s. A-V searches
may not give out an error message if the index is not built with -s.
6. Added glimpseserver to speed up queries by reading in the index ahead of
time, during July 1994.
7. Integrated compression into glimpse during July 1994. The new option to
glimpseindex can now index compressed files (those compressed with tcomp).
8. Added multipattern search for simple patterns with -w in compressed files
during August 1994.
9. Ability to take input files from command line (-F) (Sep 10/94)
10. Added byte level index support (Sep 23/94)
11. Added support for arbitrary boolean expressions (Oct 10/94)
12. Added support for arbitary filtering with -z option (Oct 94)
13. Completely integrated glimpseserver into Harvest (Jan 95)
14. Speeded up structured queries and -W option (filtering) (Feb 95)
