- 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)
