Обсуждение: Finally tsearch works ... somehow... remain a few questions
For now i am almost statisfied with my tsearch2 installation war over night somehow it seems to work, finally... 3 probably easy questions remain... 1.) Is it possible to index already filled tables? 2.)Can i have seperated indexes for different columns in a table 3.) Can i create an extra Table just for my indexes that is not included in my data table? Greetings Marcel

Seems, you need to reread documentation. http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/tsearch-V2-intro.html http://www.sai.msu.su/~megera/oddmuse/index.cgi/Tsearch_V2_Notes > > Greetings > Marcel > > ---------------------------(end of broadcast)--------------------------- > TIP 1: subscribe and unsubscribe commands go to majordomo@postgresql.org > Regards, Oleg _____________________________________________________________ Oleg Bartunov, sci.researcher, hostmaster of AstroNet, Sternberg Astronomical Institute, Moscow University (Russia) Internet: oleg@sai.msu.su, http://www.sai.msu.su/~megera/ phone: +007(095)939-16-83, +007(095)939-23-83

Most important - index consistency and native access to document metadata.
