Re: [GENERAL] text search synonym dictionary anomaly with numbers
Richard,
you should check your mapping - '1st' belongs to 'numword' and may be processed
in a different way than 'first' or '1'.

4 - this is not good. There are 4 records that do have '1st',

Re: [GENERAL] text search synonym dictionary anomaly with numbers
Oleg,
Thank you. I am sure that you have identified my problem.
\dF+ english (output below) lists my dictionary which is named
'rwg_synonym' before numword so I would have thought that my
dictionary would have normalized '1st' to '1' before the numword
dictionary was reached. Maybe this question belongs in a new thread,
but I do thank you for helping me to look in the correct place.
Best regards,
Rich

Re: [GENERAL] text search synonym dictionary anomaly with numbers
To answer my own question - my synonym dictionary was not be applied
to '1st' because '1st' is a numword, not an asciiword, and my synonym
dictionary was not mapped to numword. To map a dictionary token class:
ALTER TEXT SEARCH CONFIGURATION english
ALTER MAPPING FOR numword WITH my_synonym_dictionary, simple;
The dictionary must already have been created with CREATE TEXT SEARCH
DICTIONARY
