The default parser doesn't allow commas in numbers (I can see why, I think).
SELECT ts_parse('default', '123,000'); ts_parse
---------- (22,123) (12,",") (22,000)
One option of course is to pre-process the text, but since we can
support custom parsers I thought I'd take a look at the code to teach it
some flexibility on numbers. I'm guessing this would be of interest to
anyone wanting to support European-style "," decimal indicators too.
My "C" is horribly rusty, so can I check I've got this right? Before I
start exploring compiler errors I've not seen for decades ;-)
The parser functions (prsd_xxx) are all defined in
backend/tsearch/wparser_def.c
The state machine is driven through the TParserStateActionItem
definitions on lines 644 - 1263. Changing one of these will change the
definition of the corresponding token-type.
To add a new token-type, I'd add it to the various lists line 30-194,
then add the relevant TParserStateActionItems.
