Tsearch2 indexing question....

[mailinglists]

Hello,

First of all I want to say that I really like this tsearch2 - it's a
really great addition to Postgres!..

I am having one minor issue with it and I just can't quite figure out the
best way to solve it...

Basically I had a user enter the following string "Executive
Assistant/Network Manager"... I am unable to find this data by doing a
search for "Assistant" or "Network".. . I guess this is due to the "/"
between the two words... In any event, is there an easy solution to
this?..

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

Easy way:
comment out in wordparser/parser.l:
[[:alnum:]\./_-]+"/"[[:alnum:]\./_-]+ {
token = tsearch2_yytext ;
tokenlen = tsearch2_yyleng ;
return FILEPATH;
}

but lexeme as '/usr/local/bin/perl' will be indexed as usr, local, lib, perl.
Remember, after recompile and install, you should reindex text data.

Complex way: write your own parser.
