Description

CLIP from my whining about why the search doesn’t work in TW.


  1. 1 - why isn’t there a proper SEARCH ?


- to start this off can we at least agree on a couple things:
o standard search for - RED BALL would search on RED AND BALL
o TW does RED OR BALL – which is WRONG!!

- BASIC search should be capable of:
o RED BALL = RED AND BALL
o “red ball” = only match “red ball” as quoted
o and then, maybe RED or BALL = RED OR BALL


with a little more digging and some input from marclaporte, redflow and mose I think I have figured out the problem:

- TW supports the concept of FULL TEXT SEARCH (FT)
- this allows user to (from example above) do a search like “+red +ball” to achieve “red AND ball”.
- but these is a bug in concept in searchlib - function _find()
- if FT is set then _FIND does the right thing by doing a MATCH AGAINST sql query
- HOWEVER – if it doesn’t find any results it ALSO will do a simple (i.e. non-FT) search
o in concept this is silly since it defeats whole point of doing FT in the first place
o also, it generates an sql error because for simple search a REGEXP query is done which will choke on the + signs in the search string

Solution

BUG FIX SUGGESTION:

- remove code which does “simple search if no results”
o at least make it optional

OTHER improvements

- as I have stated before – the “NORMAL” concept of search IS my fixed version of FT search
- because of that the default search should be FT
o by that I mean “red ball” should automatically do  FT “+red +ball” without having to put + signs
