Another bug in tsearch?

От

Hi Oleg & Teodor,

This behaviour is causing problems in my search engine:

australia=# select 'banana/pineapple'::mquery_txt;    mquery_txt
--------------------'banana/pineapple'
(1 row)

In our case the forward slash symbol should really be treated as a word
break.  Are there any cases where it shouldn't be?  I can maybe only think
of 3/4, etc.

Chris

I wouldn't say it's a bug. It's a feature and called 'filename or path' :)
Probably we should interpret it as 3 lexems
'banana/pineapple', 'banana', 'pineapple' or 2 last lexems ?
Then you'll have a lot if noise for texts like mailing lists.
You could adapt parser to suit you needs, anyway.
