David,
it's not easy to hack tsearch parser, sorry. You can preparse your input
before to_tsquery,to_tsvector.

Hackers,
Is it possible to modify the default tsearch parser so that / doesn't get lexed as a
"file" token? That is, instead of this:
try=# select * from ts_debug('simple'::regconfig, 'w/d');
alias │ description │ token │ dictionaries │ dictionary │ lexemes
───────┼───────────────────┼───────┼──────────────┼────────────┼─────────
file │ File or path name │ w/d │ {simple} │ simple │ {w/d}
Ideally it'd think that / was the same as -:
try=# select * from ts_debug('simple'::regconfig, 'w-d');
alias │ description │ token │ dictionaries │
dictionary │ lexemes
─────────────────┼─────────────────────────────────┼───────┼──────────────┼────────────┼─────────
asciihword │ Hyphenated word, all ASCII │ w-d │ {simple} │
simple │ {w-d}
hword_asciipart │ Hyphenated word part, all ASCII │ w │ {simple} │
simple │ {w}
blank │ Space symbols │ - │ {} │
[null] │ [null]
hword_asciipart │ Hyphenated word part, all ASCII │ d │ {simple} │
simple │ {d}
(4 rows)
Possible? Or would I have to write a completely new parser just to change this
bit?
Thanks,
David
Regards,
Oleg
